This toy has a body made of molded PU coated plastic, and features a nubbled silicone head. The head is highly textured with a myriad of little "nubs" that make the toy look a little bit like a hair brush, which provide gentle stimulation. The nubs are made out of very soft silicone. It's not porous, scentless, and tasteless, however you cannot sterilize it properly because of the plastic areas of the toy. I would recommend cleaning with anti-bacterial soap and water, or toy cleaner.
This toy is interestingly shaped, almost like a hairbrush, with a bulbous handle and then the textured head mirroring the shape of the handle. On the handle there is a single button, which turns the toy on and cycles through the vibration modes, to turn it off you must hold down the button (which is a little fiddly if you need to turn it off quickly) The shape of this toy is ingenious, it's very comfortable to hold, and makes for easy play with no wrist pain at the end (and seriously, who enjoys post masturbation wrist cramps). My only objection to this toy is the battery case which is incredibly hard to get on and off, and yet is oddly prone to popping off in the middle of play.
The controls are simple and easy to use, a single button cycles through various vibration modes. The performance is fairly good, though I've noticed an odd tendency for the vibration to "change" when the toy is held at certain angles, not getting more powerful or less powerful, but at certain angles the vibe is significantly louder and "buzzier" and at others it's quieter and "rumblier". It's not waterproof, and features a variety of vibration functions, including roller coster, pulsation, and a sort of "dot dot dash' vibration pattern.
Due to the mixed material I'd go with warm water and anti-bacterial soap on this toy. As well it's only compatible with water based lube (it's silicone) and should probably be stored in a baggie as it's a bit of a lint magnet. It's also a little troublesome to clean because of all the texture.
This is a middle of the road sort of a vibe, it's not "knock your socks off" fantastic, nor is it "Throw it at the wall" terrible, it's... average, the texture is nice, it's a nice way to add a little variety to a toy box, but it's nothing too special.
