Some of the most fun I've ever had with a toy like this ever. From the app, the controller, and the perfect sized toy and soft silicone, it's made the perfect recipe!Fits exactly as it should around the base in a unique way I've never experiences before, and the thickness is a nice balance aswell.Whether you like it fast or slow, speed and variations are all up to you.Battery lasts a looong time and works just as it should time it runs out. Highly recommended, you won't regret!
