It has a really nice design and is easy to use. Missionary position works best otherwise it does have the tendency to slide out. The inside "arm" could stand to be longer which I think would help with the sliding out issue. Also, I wish the description was a little more clear, we were under the impression both arms vibrated, but only the outside arm does.
My wife and I absolutely love this. The occasional challenge to keeping it in place, also drives a more intimate connection, and a variety of positions.
I purchased this about a month ago, and my Fiance and I love it! Its soooo much fun to be able to give him the "power" while I enjoy the "pleasure". The vibes are strong and the material is soft to the touch.
The wife wanted something we could enjoy together, and this has been it! Also an excellent toy for public foreplay, although the remote is a little loud and we've been caught a couple of times... Would still highly recommend!!
the only negative thing I have to say is that it may leave your penis with some irritation but nothing major and stopping to relube would probably prevent this. Other than that its incredibly fun to use the remote to tease your partner. Works best for foreplay or if you just get right into it.
