U.F.O. TW Review: The Downsides, the Noise, and My Honest Verdict

U.F.O. TW at a glance. Good: a new sensation, great with audio works, slow mode feels real, easy to clean and hard to break. Not so good: few synced videos, both cups move the same, about 60 minutes of battery, ultra-slow mode needs the app.

I'm someone who never had much interest in nipple play — before this, I almost never touched my nipples at all. These are my honest impressions after actually using the U.F.O. TW.

It does have real downsides, so if you haven't bought one yet, please read this before you do.

If you want to know how I bought a genuine unit (not a fake) at the lowest price, here's that story:

The Downsides of the U.F.O. TW

5 downsides of the U.F.O. TW: some VR headsets won't sync, few synced videos, both cups always move the same, battery lasts about 60 minutes, ultra-slow mode needs the app.

It won't sync with my SKYWORTH PRO VR headset

My own VR headset, the SKYWORTH PRO, would not sync with the U.F.O. TW.

Adult Festa's device compatibility chart; the U.F.O. TW row shows an X for both SKYWORTH headsets — Adult Festa's compatibility chart as of March 1, 2022 (screenshot, in Japanese). The U.F.O. TW row shows an X for both SKYWORTH headsets.

It does work with DPVR headsets. As of September 2026, Adult Festa's setup page still lists the SKYWORTH-4D S801 and Pro-802 as unsupported, while the DPVR-4D and DPVR-4D Pro are supported.

Update (September 2026)
As noted above, Adult Festa's official FAQ lists only the DPVR-4D and DPVR-4D Pro as supported VR headsets.
Headsets such as PICO and PSVR are not supported.
Check your headset's model number before you buy.

I did work out a trick to make it sync with the SKYWORTH PRO anyway — I explain it in this article:

How to Sync the U.F.O. TW with VR Headsets, Phones and PCsHow to sync the VORZE U.F.O. TW with Adult Festa on DPVR headsets, phones and PCs, a SKYWORTH workaround, fixes when it won't sync, and videos I recommend.Read the article ›

There aren't many synced videos

When I wrote this in March 2023, only about 80 titles on Adult Festa (a Japanese VR video site) could sync with the U.F.O. TW. That's a real weakness.

Fans have also made CSV files that sync the U.F.O. TW to audio works, which widens what you can enjoy a lot.

The U.F.O. TW has been selling well, so Adult Festa may add more synced titles once they see the demand.

Update (September 2026)
To find synced titles on Adult Festa, look for the bracketed tag “【U.F.O.TW】” or “U.F.O. sync” (written in Japanese) in the title.
I couldn't confirm how many synced titles there are as of September 2026.

You can also buy nipple-play videos on FANZA (Japan's biggest adult video store) and simply enjoy them without syncing.

If you don't plan to sync at all, the cheaper U.F.O. MOBILE (¥15,620 (about US$99)) is an option too — but it's popular, and it was often sold out when I was shopping.

Update (September 2026)
On September 25, 2026, the U.F.O. MOBILE was in stock at NLS.
It's limited to one per customer.
For how the TW, MOBILE and MOBILE MEN differ, see my U.F.O. TW vs. U.F.O. MOBILE comparison.

The two cups can't move differently

The two U.F.O. TW cups side by side with their lights on

At first I assumed the U.F.O. TW could move the left and right cups independently. It can't — by design, both cups always make the same movement.

So even when the video shows only the left nipple being teased, the right cup moves too. That takes away some of the realism.

With videos where two partners work on both nipples at once, it's not a problem at all — so I've learned to live with it.

Update (September 2026)
If you switch the TW's cups on one at a time, they automatically fall into the same movement.
If you won't use video sync and care most about the left and right moving differently, look at the U.F.O. MOBILE and MOBILE MEN.
With those, you can set the movement and suction strength separately for each side.

It's a bit of a hassle, but I did find a way to make the two cups move differently. I explain it in this article:

How to Use the U.F.O. TW: Charging and Controls (with Videos)How to use the VORZE U.F.O. TW, with videos: the 5 modes, pausing, warming, attachments, wearing it, cleaning, charging, storage and a left/right trick.Read the article ›

The battery only lasts about 60 minutes

With only about an hour of battery, I kept thinking “When is it going to die?” and caught myself rushing: “I have to finish before it runs out!”

A full charge takes about 2.5 hours (per VORZE's spec sheet), and if it dies mid-session the mood is gone, so keep an eye on it.

Update (September 2026)
Some owners say the battery life dropped the more they used it.
There are also posts on X saying it doesn't even last an hour at fast rotation.
Charge it fully right before you use it.

Making it last longer than 60 minutes would mean bigger, heavier cups, so…

…I guess that's the price of keeping them light.

The ultra-slow mode needs the app

Controlling the U.F.O. TW from the smartphone app

The built-in patterns include slower movements, but with the buttons on the cups alone I couldn't get the ultra-slow mode I describe below.

When I first wrote this, the app was Android-only, which was a real downside for iPhone users. That has changed: according to VORZE's spec page (checked September 2026), the U.F.O. TW now works on iPhone too, through the BleToyBox app.

Update (September 2026)
VORZE's official Android app, “VORZE Controller,” lets you choose from 7 movement patterns and 7 speeds.
For controlling the TW from an iPhone, VORZE points users to “BleToyBox.”
However, BleToyBox is not an official VORZE app.
Video sync works on iPhone too.

The Upsides of the U.F.O. TW

A completely new sensation

A U.F.O. TW cup in front of a VR video scene

Syncing the U.F.O. TW with a VR headset really felt like a woman was licking me all over. As someone who loves being teased by several partners at once, it suited me perfectly.

Plenty of the VR videos that sync with the U.F.O. TW feature several women at once, too. I stroked myself at the same time and finished hard.

Using it with DLsite audio works is dangerously good

It might even beat VR… I had no idea audio alone could turn me on this much.

With someone licking my ears while my nipples are being teased, I finish almost instantly.

There's a huge range of audio works you can use with the U.F.O. TW — I've ended up buying audio works that cost more than Adult Festa videos.

They felt great synced with the A10 Cyclone, too.

That said, driving the U.F.O. TW with CSV files is a bit of a hassle.
Here's exactly how to do it:

Update (September 2026)
“Web CSV Player,” the tool most people use to drive toys from audio CSV files, turned its free version into a trial version on April 21, 2024.
The trial version can't play tracks longer than 3 minutes.
The unlimited version is sold as a one-time purchase on Fantia (a Japanese creator-support site).
A bug that stopped the TW from connecting was also fixed on November 18, 2024.
💡 If it wouldn't connect for you before, give it another try.

The slow mode feels amazing

The low-speed motor is the U.F.O. TW's biggest selling point. Its slow, random movement really feels like a real tongue.

That's something cheap toys just can't do.

This alone makes it worth buying, even at this price.

The ultra-slow mode needs the smartphone app (Android when I tested it; iPhone now works via the BleToyBox app).

Cleanup is easy

Rinsing a U.F.O. TW attachment under the tap

Cleanup is much easier than with the A10 Piston or A10 Cyclone. It isn't a closed sleeve like an onahole, so it's easy to wash.

Having no cables like the U.F.O. SA also makes cleanup easier, and you can simply rinse it under the tap (VORZE rates it IPX5 waterproof).

It's less likely to break

With no cables, it's less likely to break than the U.F.O. SA.

On the U.F.O. SA, the cable often got damaged when a cup slid off my chest.
Because the two cups on the TW are separate, they're easier to handle, too.

Update (September 2026)

Failures still happen, even without cables

Reviews on NLS and posts on X include reports that one of the cups stopped working.
Having no cables doesn't by itself mean it won't break.
Even after the warranty period, VORZE still accepts the TW for paid repairs.

Here's my guide to using it:

U.F.O. TW vs. U.F.O. SA vs. U.F.O. MOBILE: Feature Comparison

U.F.O. models compared: price, battery, waterproofing, wireless and warming for the U.F.O. TW, U.F.O. SA and U.F.O. MOBILE

Better than the U.F.O. SA: wireless, warms up, lighter, buttons on the cups, stronger suction

[U.F.O. SA → U.F.O. TW] What was improved

[1] The U.F.O. SA had lots of broken-cable failures; the TW is wireless, so cables no longer get in the way
[2] The warming function means no more “cold shock” — it feels closer to body temperature
[3] Going wireless made it lighter (you can even wear just one cup)
[4] The controls moved from a separate controller to buttons on the cups
[5] Stronger suction (it works for men and flat chests too)

I received an email from NLS, the U.F.O. SA's only official retailer, announcing that the U.F.O. SA had been discontinued.

Update (September 2026)

Corrections: prices and charge time

The comparison table above already shows current prices.
Here are NLS's prices on September 25, 2026:

Product	NLS price	Features
U.F.O. BASIC	¥9,988 (as of September 2026)	Wired, runs on 4 AAA batteries
U.F.O. MOBILE	¥15,620 (about US$99)	Suction; left and right can move differently
U.F.O. MOBILE MEN	¥16,390 (about US$104)	A MOBILE with shallower cups, made for men
U.F.O. TW	¥50,820 (about US$323)	Warming and video sync

Also, VORZE's spec puts the U.F.O. MOBILE's charge time at about 2.5 hours (the table above shows this).
A simple rule: if you'll use video sync, get the TW; if not, choose the MOBILE or MOBILE MEN.

Unboxing the U.F.O. TW!

The U.F.O. TW delivery bag left in the parcel locker

First, here's the package as it arrived.

You can see how I ordered it here:

I asked for delivery to my parcel locker without ringing the doorbell. If you request it when ordering from NLS, they'll also add a discreet “privacy” sticker.

The shipping box with NLS's discreet privacy sticker

↓↓ Check that the box is properly sealed in its plastic wrap.

The U.F.O. TW box still sealed in plastic wrap

If the wrap is missing, the box may have been opened before.

When I bought mine, NLS was the only place selling the U.F.O. TW (as of September 2026, Adult Festa also sells it in a set with a VR video). If you ever buy from a site you don't know, make sure the box has the “RENDS” hologram seal.

Update (September 2026)
As of September 2026, there is also a U.F.O. TW product page on Amazon Japan, not just at NLS.
I couldn't confirm who the seller is or the price, though.
I recommend buying from NLS, the official store.

↓↓ I also bought the official U.F.O. TW chest supporter from NLS.

Here's what comes in the box:

The two cups
Cradle
Two kinds of attachments (propeller and brush)
Charger (AC adapter)
Plug attachment for overseas outlets (not needed in Japan)
Lotion

Everything in the U.F.O. TW box laid out

↓ The lotion is 50 ml, so it should last about 10 sessions.

The 50 ml bottle of VORZE Smooth Lotion included with the U.F.O. TW

At the time, adding a bigger bottle of lotion to my U.F.O. TW order got me free shipping, so I'd recommend buying one together.

Update (September 2026)
The TW alone now qualifies for free shipping, so there's no need to add lotion just to avoid the shipping fee.
As of September 2026, NLS ships free on orders of ¥5,000 or more.

VORZE Smooth Lotion

There was a user guide, but no warranty card. Don't worry about that: VORZE's support page says the U.F.O. TW is covered for 3 months from the purchase date even without a warranty card, as long as you can show proof of purchase (the warranty is valid in Japan only, and second-hand units aren't covered).

Update (September 2026)
As mentioned above, even without a warranty card, the manufacturer's warranty runs for 3 months from the purchase date.
You'll need something that shows the purchase date, such as a receipt, so keep it.
NLS exchanges initially defective units within 8 days of delivery, as long as the item is unused.
Just checking its condition and that it works still counts as unused, so check it as soon as it arrives.
For what to do if it breaks, see my article on U.F.O. TW repairs and warranty.

It comes with a plug attachment for use outside Japan — handy if you live abroad.

Two types of attachments come in the box.

The U.F.O. TW brush attachment in its pack

The U.F.O. TW propeller attachment in its pack

You get two of each type, and you can even put a different attachment on each cup.

How Loud Is the U.F.O. TW?

At maximum power on a quiet night, you might notice the motor a little. But it's quieter than a rotor or vibrator, so I don't think you need to worry much.

Surprisingly, it couldn't be heard in the next room. When it's synced to videos, the movements are rarely that intense, so noise isn't really an issue.

It does make some sound, so if it bothers you, wear noise-cancelling headphones.

Headphones also make it easier to lose yourself in the scene, which gets me even more excited.

For step-by-step instructions, see this article ↓↓

Is the U.F.O. TW's Material Soft?

Pressing the soft silicone of a U.F.O. TW cup

It's made of very soft material, so it sticks to your chest easily. Its suction is stronger than the older U.F.O. SA, so it falls off less often.

It's tough, too — even rough handling hasn't torn it.

However, the suction does seem to weaken over time. Wipe it with water regularly to keep it sticking well.

Update (September 2026)
Some also say that because the cups are deep, they struggle to reach the nipples on a flat male chest.
There are also reviews saying the rotation stops if you press the cup on too hard.
One post on X said that by adjusting how deep it sucks in, they could fix it where it just lightly touches the nipple.
💡 When you put it on, try a few positions and find one where you aren't pressing it on too hard.

Even with a sports bra (supporter) on, the cups won't reach your nipples if the suction is weak.

A post by @papurinpapi about the U.F.O. TWThis post is no longer available on X.

To be honest, there weren't many reviews on X.

Update (September 2026)
Posts on X from 2024 to 2026 do include first-hand impressions from TW owners.
Some praise the warming function and the strong rotation.
Others point out that buying a new one after it breaks is expensive.

They also include “HANA,” which is close to the rose-shaped attachment that was popular on the U.F.O. SA.
For details, see my article on U.F.O. TW attachments.

Negative reviews

The run time is a bit short
Fewer patterns than the U.F.O. SA
The cups are bigger, so it's harder to find the right spot
Not many synced videos
It stops if there's too much resistance

Stronger suction than the U.F.O. SA
People love that it's cordless
It feels so good you can't help moaning
Bought it for dry orgasms
The cradle's warming function gets good reviews
You don't have to play with your nipples yourself, so you can focus on the video
It stays on without a supporter (sports bra), even on a flat chest
The dedicated cradle makes storage easy

Former U.F.O. SA users always say they're glad the cables are gone.
The U.F.O. SA had so many cable failures…
