This rabbit looks pretty awesome, at first glance. Although seemingly there isn't much to insert, it will fool you. First about the design. There is an on/off button. Don't believe it. It does not turn the device on, only off. You have to press the + buttons on either side in order to start it humming.

One problem I found was in the battery pack. It simply slides into the butt of the toy. There is nothing to actually hold it in place. So if you really get to rocking with this toy, it may slip out. From 60 to 0 in 1 second. No fun.

The plus buttons will cycle through the patterns available. While there are obviously 8 different options for vibration, there seems to be only 4 for rotation. Although it might be that the latter rotations are similar enough that it is not noticeably. Rather than the lights on either side showing you the currently used setting, they flow up and down to simulate intensity, I believe. So the first level of rotation automatically jumps to 4, the next goes to 6.

One nice feature I found is that if the rotating beads are squeezed too tightly, they will shut down the toy entirely. While it is annoying during use, it can save you from burning out the motor. Which is a very thoughtful feature.

I prefer using a toy like this with a condom. It makes cleanup a lot easier. However if you prefer taking it bare, then make sure you clean it well with soapy water. While it is waterproof, I wouldn't submerge it. The fact that the battery pack can easily slide out is a strong indicator of possible accidents on that front.

The little rabbit head has a great vibration. It was nice to feel tickling below my balls while I used the main part of the toy for more important endeavors.
