Some toys vibrate, some thrust, some rotate. This one does all three at once, giving you a prostate massager that moves the way you want without you having to do the work yourself.Insertion is easy thanks to the smooth surface and curved shape, with a flared base that keeps things comfortable and secure from the start. Once it's in place, the gently swollen tip settles right against the prostate, while dual motors get to work, one in the shaft and one at the base, so vibration and thrusting and rotation all happen together instead of one at a time. The flexible build moves with you rather than against you, and a simple button control lets you shift through the speeds until you land on the one that works. A memory chip keeps track of your last setting, so next time you pick it up, it starts right where you left off instead of making you scroll back through modes.This CalExotics thrusting rotating probe is made from silicone and ABS, phthalate-free, fully waterproof and USB rechargeable, and pairs well with a water-based lube. As far as anal probes go, this one does the work of three toys in one.
