The little spikes on the roller give a surprisingly sharp, even tingle all the way up the arm, way more intense than I expected from something this compact. Rolls smoothly too, no snagging.
Ellie★★★★☆
The pinwheel rolls smoothly and the spikes give a nice sharp sensation without breaking the skin, which is exactly what I wanted. Only complaint is that it's smaller than I pictured, so I have to work it over a wider area bit by bit.
Scarlett★★★☆☆
The spike wheel spins smoothly enough, but the handle feels lighter and more plasticky than I'd like for the price. It does the job for light sensation play, though I wouldn't push hard with it.
