The little ridges along the shaft do exactly what they promise—targeted and precise, no guesswork needed. For something this small it’s surprisingly rumbly, and since it runs on batteries I can toss it in my bag without hunting for a charging cable.

Took it on a weekend trip and the battery-powered design meant zero charging cables to pack — just popped in a battery and it was ready. For something this small, the motor’s surprisingly steady, and the gentle wave on the shaft made aiming easy even in a hurry. Five stars from me.

The soft ridges along the shaft hit exactly the right spot, and for something this small it packs a surprising punch. I threw it in my purse for a weekend trip and it barely took up any room, which made the spontaneous fun way too easy.
