I bought this toy because I am a sucker for new experiences, and this turned out to be exactly what it was promised to be: a truly unique toy!

There are three buttons: "FUN", "+", and "-". The "FUN" button functions mostly like an on/off switch, and the "+" and "-" are used to change the mode. There are 10 different patterns, but I was disappointed that there no way to adjust to speed or force of the thrusts within each mode (hopefully generation 2 will have more variability).

Between the girth and the matte texture of the silicone, I had to use a lot of water-based lube with this!
I was pleased that this toy required little user effort. I was able to basically "set it and forget it" once I got it where I wanted it. When I tried to manipulate it manually, it really just seemed to impede the function of the toy.

The thrusting action itself feels great. Being the first of its kind, it's difficult compare what it does to anything else. It feels like it must have a hollow section in the middle, and there is something small and heavy "banging around" (albeit in a very precise way) inside of it, causing it to push forward and back. It is very quiet, and I was impressed by how powerful it is. I'm someone who finds that most vibrators, when used externally, are too powerful for me, so I was surprised that I enjoyed the more intense settings on this toy from the first use.

This toy has very specific instructions that it is not to be used anally. I wonder if there is a reason for this besides the fact that it does not have a flared base? If I were a less cautious person, I might be tempted to try it.
