"The Persuader"

"The Persuader" weighs 36 grams and measures 11.6 centimetres, the sort of size that goes into a drawer or a bag without announcing itself. Body-safe silicone over an ABS core, in blush.

If you've never found anything that suited you, the shape is worth trying before you spend more. The tapered end concentrates everything into a small area, and the angled tip means you can change the pressure by rolling your wrist instead of repositioning. Ten settings, all from one button, and 36 grams is light enough to hold there as long as you like.

Charging takes about three hours and gives you roughly the same again in use. Rocks-Off has a two year guarantee on it. One thing worth knowing: no waterproof rating is published for it, so it isn't a bath or shower option.
