"The Limousine Driver"

The handle on "The Limousine Driver" has a padded cushion texture rather than a smooth finish, which gives your fingers something to grip once lubricant is involved.

It's a small one: 10.9 cm end to end and 2.2 cm across, with 7.1 cm of that insertable, so you can use it outside or in. The silicone is soft and the body flexes. It takes up about as much room as a lipstick, and the travel lock stops it waking up in your luggage. For a first buy, or a second one that lives in a suitcase, that matters more than it sounds.

One button runs it, and the speed climbs by degrees while you keep it pressed rather than stepping through set patterns. It charges over USB. Use a water-based lubricant with the silicone. BMS Factory publishes no waterproof rating for it, so don't take it into the bath.
