Why does a couples vibrator need two motors? A wearable couples vibrator has to do two jobs. Its outer arm stimulates the clitoris, and its inner arm sits beside a partner during penetration. With one motor, the vibration has to travel along the whole toy and loses strength on the way. With two, each arm has its own source. In TIANI DUO the motors run at different frequencies, 130 Hz and 105 Hz, so the sensation inside feels distinct from the one outside.
LELO TIANI DUO: one motor for each of you
TIANI DUO is a dual-action couples vibrator with two motors that work in tandem. One sends vibration to the clitoris and the other to the penis, so each partner gets a direct sensation instead of a shared leftover. The soft body bends to sit comfortably on different shapes, and eight vibration settings give a wide spread of intensities.
The wireless remote has SenseMotion built in, which means a flick of the wrist turns the vibration up. TIANI DUO is 100% waterproof, charges by USB in two hours and runs for up to two hours on a full battery.
Best for: Couples who found single-motor wearables too faint on one side, and partners who want to climax close together. The inner arm is worn in the vagina during penetration and the outer arm rests on the clitoris.

How to use
Start with a two-hour USB charge and put the two AAA batteries into the remote. Rub water-based lubricant over the inner arm. Insert that arm into the vagina and position the outer arm on the clitoris, flexing the body until it sits snugly. Switch on and choose from the eight settings with the remote. Your partner then enters beside the inner arm, where the second motor is felt along the penis. Whoever holds the remote can flick their wrist to push the intensity higher.
Care
- Only use water-based lubricant with the silicone body.
- Wash before and after each use with warm water and mild soap or a toy cleaner.
- Do not boil it or put it in a dishwasher. It has two motors and a battery.
