How to Use the U.F.O. TW: Charging and Controls (with Videos)

In this article you can see exactly how the U.F.O. TW moves, in videos (with sound).

I'll explain how to use the U.F.O. TW in this order:

The controls
Warming it up
Putting on the attachments
Putting it on your chest
Charging
Storage

I'll also show you a trick to make the two cups move differently.

To sync the U.F.O. TW with videos from Adult Festa (a Japanese VR video site), see this article:

How to Control the U.F.O. TW (with Video)

The two U.F.O. TW cups with their power lights glowing blue

Each U.F.O. TW cup has just one button.

Basically, the two cups won't move differently.

The two cups are always synced and make exactly the same movement.

The cup you turn on first becomes the one that controls both.

The cup you turn on second has no control.

So there's no dedicated “left cup” — either cup works on either side.

Update (September 2026)
If the left and right cups fall out of step, keep them within 1 m of each other with nothing in between (maker's FAQ).

What each mode does (video)

VORZE's diagram of the U.F.O. TW's 5 movement patterns, from slow to fast — VORZE's chart of the 5 movement patterns (screenshot; the Japanese caption reads "5 movement patterns"). Gray arrows = slow, pink arrows = fast.

The video has sound, but you can mute it.
You can also hear how loud the U.F.O. TW's motor is.

Each press of the button switches to the next of these movements:

White mode

Pattern 1, white: slow clockwise rotation

Rotates slowly clockwise.

Light blue mode

Pattern 2, light blue: slow rotation that changes direction

Rotates slowly and sometimes switches direction.

Purple mode

Pattern 3, purple: fast clockwise rotation

Rotates fast, clockwise.

This is the mode I use when I want strong, nonstop stimulation.

Yellow mode

Pattern 4, yellow: a mix of slow, fast and reverse rotation

Rotates slowly, then fast, then in reverse.

To me it feels close to random.

Red mode

Pattern 5, red: random speeds and directions

Speeds up and reverses at random.

Can you pause it?

Each U.F.O. TW cup has only one button, so there's no pause button.

Keep pressing the button through the cycle; when the light turns green again, it stops.

The U.F.O. TW Android app can pause it.

While it's synced to a video, pause the video to stop the U.F.O. TW as well.

While it's synced, you can't pause it with the button.

Can you force it to stop?

Even while it's running, press and hold the button to force it off.

This works even while it's synced to a VR video.

* Controlling it with the U.F.O. TW app gives you more options than the buttons, such as the low-speed mode.

Here's how to control the U.F.O. TW remotely with the app:

Update (September 2026)
The official Android app, “VORZE Controller,” lets you choose from 7 movement patterns and 7 speed levels (according to NLS).
For iPhone, the maker points users to an unofficial app, “BleToyBox.”

[Trick] Making the Left and Right Cups Move Differently

Here's how the U.F.O. TW works: when you turn on one cup and then the second, the two cups sync with each other over Bluetooth.
If you use aluminum foil to block that Bluetooth sync between the cups, they'll move differently.

Wrap just one cup in aluminum foil before you turn it on, and the cups won't sync — so they move differently.

Update (September 2026)
Blocking the sync with aluminum foil isn't a method the maker recommends.
The models that officially support different movements on each side are the U.F.O. MOBILE and MOBILE MEN (according to the maker).
For the differences, see my U.F.O. TW vs. U.F.O. MOBILE comparison.

How to Warm Up the U.F.O. TW in the Cradle

Pressing the cradle button, which glows green, to start warming

Press and hold the cradle button: it turns green and warming starts.

The power cord has to be plugged into the cradle.

After 30 minutes, the heating turns off automatically.

Start warming it up a while before you plan to use it.

Update (September 2026)
A correction to the warming time above.
According to the maker's specs, it heats for 30 minutes, keeps warm for another 30 minutes, and then switches off automatically.
To stop it partway, hold down the cradle button (according to NLS).
It takes about 15 minutes to reach skin temperature (according to the maker).

It warms them to a comfortable temperature, never too hot.

Unless it's winter, you don't really need the warming function.

The lotion is cold, so you could also warm the cups after applying lotion — but then lotion may get on the cradle.

How to Put the Attachments on the U.F.O. TW

You can even put a different attachment on each cup.

Line it up with the bumps and grooves and snap it on.

It's held on firmly by a magnet, and with the bumps and grooves it almost never comes off during use.

Update (September 2026)
The U.F.O. series accessory sets (¥2,728 each) also fit the TW with the TW adapter attachment that comes in the set.
TW-only accessories cost ¥1,870 each at NLS (as of September 25, 2026).
For how to choose, see my U.F.O. TW attachment comparison.

How to Put the U.F.O. TW on Your Chest

First, put lotion on the U.F.O. TW attachment.

Be careful: if you get lotion on the cup (the bowl) itself, it won't stick to your chest.

One pump was plenty.

Something like the U.F.O. TW supporter (sports bra) really is a must.

Wearing the black chest supporter (sports bra) over the U.F.O. TW cups

That's because otherwise the cups may fall off.

A fall can also cause a U.F.O. TW breakdown.

When I use it together with the A10 Cyclone or A10 Piston, I move around quite a lot, so the suction weakens and I often end up dropping a cup.

If you use it lying down, you probably don't need the bra.

You have to press it on pretty hard, or it won't reach your nipples.

It's tricky at first, but you'll get the hang of it.

Update (September 2026)
Some NLS reviews say that if you press it on hard, the rotation stops.
Start with it sitting lightly, then press it in little by little to find the spot where it hits.

The annoying part is that I keep hitting the power button when I press the cup against my chest.

After use, it leaves quite visible round marks on your chest, but they fade quickly.

Here's my review of the supporter you wear over your chest:

How to Clean the U.F.O. TW

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

Cleaning is very easy: just take off the U.F.O. TW attachment and wash it.

No need to worry about your family finding out, either.
For the cups themselves, simply wiping them with a wet tissue keeps the risk of breaking them lower.

It's waterproof, but I'd still avoid washing it too much.

I've actually seen people whose units broke.

Update (September 2026)
According to the maker's specs, the TW is waterproof to IPX5 (a rating for withstanding jets of water from any direction).
NLS reviews also mention the magnetic charging contacts rusting.
💡 After washing, wipe off the water well and let it dry before you charge it.

Your chest will be covered in lotion, so wipe it off with a tissue.

After about 20 minutes of nipple play they're red, but they don't hurt.

Keeping the cups clean makes them stick better — and feel better.

How to Charge the U.F.O. TW

Plugging the charger into the back of the cradle

Plug the charger into the cradle and set the U.F.O. TW in it; it's fully charged in 2.5 hours.

Watch this video to see how to set the U.F.O. TW in the cradle to charge it ↓↓

It won't charge unless the magnets connect properly, so be careful.
When it's charging properly, the green light blinks.

When it's fully charged, the green light goes out.

A full charge gives you only 60 minutes of use — that's short.

Try to charge it before each session so the battery doesn't die halfway through.

When the battery runs low during use, the power light on one of the cups turns red, and I got so anxious — “I have to come quickly!” — that I couldn't lose myself in it.

You can also start the warming function while the U.F.O. TW is charging, by holding down the cradle button.

The underside of the cradle has a fan vent to let the heat out.

The cradle gets hot when you use the warming function, so be careful.

The charger is different from the ones for the A10 Piston SA+ and A10 Cyclone SA+, so you can't share them (as of March 2023).

Update (September 2026)
If you lose or break the TW's charger, you can buy a “U.F.O. TW charger” on NLS's “VORZE series spare parts” page.
On September 25, 2026, it was ¥3,663 and in stock.
💡 Make sure you choose a charger labeled “for U.F.O. TW.”

How to Store the U.F.O. TW

I cover it with the U.F.O. TW chest supporter and keep it in the closet.

I put it chest-side down, so it's harder to tell it's a bra.

If you don't mind the effort, keep it in the box it came in.

Does the U.F.O. TW Come with a User Manual?

The one-sheet U.F.O. TW user guide — The user guide that comes in the box (Japanese side). The back is in English.

A user guide comes in the box.

It's just this one sheet.

There's no U.F.O. TW warranty card (there is still a warranty, though — see the update below).
The back of the guide is in English.

Update (September 2026)
You can download the user guide from the maker's official website.
Even without a warranty card, the maker's warranty lasts 3 months from the purchase date.
To use it, you need a receipt or another document showing when you bought it.
