Bought as a present for my husband, kind of feel bad I get all the good toys, you know..
The battery part was broken, and it didn't go. So he had to fix it before he could have a go with it.
Anyways, the best bit about the whole thing is the 'donut' mouth that goes where you put your dick in, he said that feels good but that's about it. Once you get past the entrance, theres nothing to stimulate other than the 'sucking' - which really only builds up pressure inside the casing. You can't move it up and down, unless you hold the release button down (not easy). It really didn't get him going at all, and he tried a few different ways to see if he could get into it... anyway, if you're looking for a pump - cool - but otherwise, don't waste you're money.
I'm pretty disapointed, and feel stink that it wasn't very good for him, and he feels bad because he thinks it's shit and I tried to surprise him.
