Synchronization rate: 400%. TamaToys built an electric piston unit and themed it after the Eva. The pilot does nothing. The unit does everything. As intended.
Why it costs what it costs.
Amazon's "auto" sleeves are a hand-crank in a plastic case that dies the second you actually need it. This is a genuine TamaToys electric piston unit — real motorized stroking, body-safe sleeve, EVA Unit-01 themed for the fans, plain packaging, 100-day return. You're not paying more — you're paying once, for a unit that won't go AT Field on you mid-session.
Built for the collection
Most weebs don't own one onahole — they own a hangar bay. Manual sleeves, a torso, maybe a hands-free unit. This one earns its spot two ways: it's a genuine electric piston device, and it's collector-grade EVA fan service from TamaToys. The kind of thing that's half toy, half shelf trophy. Same body-safe TPE quality, with a paint job your inner 14-year-old will respect.

FAQ
Is the packaging actually discreet?
Yes. Plain brown outer carton, no anime art, no Eva graphics, no NERV logos, no company name. Return address reads "ADP Distribution." Inside the outer carton is a sealed inner box — the themed product box stays sealed inside that. It looks and weighs like a cordless power tool.
What does the "electric piston" actually do?
The motor drives an automatic stroking (piston) motion so you don't have to — six speeds and three stroke-length patterns. It's the auto-stroker mechanism, fully motorized, not a hand-crank gimmick. Set the speed, hit start, and the unit handles the rhythm.
Is the EVA theme official TamaToys?
It's a genuine TamaToys-made unit with EVA Unit-01 styling — the collector fan service is part of the appeal. Treat it as both a working device and a shelf piece. The themed art stays sealed inside the discreet outer carton, so the fandom is for your eyes only.
Is it really USB rechargeable?
Yes. Li-ion battery, real cable in the box, roughly 120 minutes to full and about 60 minutes of run time. No AAs, no proprietary brick. Charge it off your laptop between sorties.
Is the material body-safe?
Yes — the removable sleeve is body-safe TPE (phthalate-free, latex-free) and the shell is ABS. Same material grade used by major Japanese manufacturers like TamaToys, Magiceyes, and Rends. Rinse with warm water + toy cleaner before first use.
How do I clean it?
Pop the sleeve out and rinse with warm water and a few drops of toy cleaner or mild unscented soap. Air-dry inside-out, then dust with cornstarch (not talc). Wipe the motorized shell with a damp cloth — never submerge the motor housing.
What lube should I use?
Water-based lube only. Silicone-based lube degrades the TPE sleeve over time and ruins the feel. Pjur Aqua, Wicked Aqua, ID Glide, or any drugstore water-based brand works fine.
How loud is it?
Under 50 dB — quieter than a desk fan and well under the volume of a certain anime's emotional dialogue. Thin walls and curious roommates aren't a problem. Nobody's hearing this through a door.
Is the sleeve removable and replaceable?
Yes — the body-safe TPE sleeve pulls out for easy cleaning and can be swapped if you want a fresh texture down the line. The motor unit is the investment; the sleeve is the consumable. Cleaning is simpler and the device lasts far longer this way.
What's your return policy?
100 days. If it doesn't work for you for any reason, send it back within 100 days of delivery for a full refund. No questions, no "why." Hygiene exception: the sleeve must be in resalable condition (cleaned), and the electronics undamaged.
