This is the first prostate massager I ever bought or tried. The size and shape makes it great as an intro into prostate play. I used it both solo and with a partner. Solo, the shape of the handle and position of the controls made it easy to work with. I didn't like it as much with a partner as the form factor made it hard for her to move around, manipulate, and change the speed/vibration rhythm. Speaking of vibration, the motor is definitely strong enough to get things humming, and the variable speeds and pattern are fun to play with.

The toy is a hard black plastic and is safe to use with silicon lube. I think the rigidity of it also made it work very well as first-time anal toy (for masturbation) as, once it is lubed, it is fairly easy to insert and move into place (side note - I recommend sitting on a towel lest you leave lube marks on the couch - not that I did that...). The on/off for the vibrator is located on the top of the handle, which rests close to your perineum, as such it is fairly easy to switch on once you have it in. The power button also controls the speed/rhythm, so you can increase speed without much problem. As it is waterproof, cleaning is a breeze - a little soap and water in the sink, wipe it off, and back in the drawer (or sex-toy repository of choice).

Unfortunately, there are two downsides - the battery cap pops off frequently, which is slightly annoying (especially mid-use - nothing like shuffling across the room with a vibrator up the butt chasing a little plastic cap while simultaneously trying to keep the batteries from falling out). More aggravating is that the motor crapped out (pun intended) after only 20 or so uses. I know any kind of vibrator will fail eventually, but this seems pretty fast. Nonetheless, it was enough to figure out I like prostate massagers, and get me to start to shop for a higher-end one.
