The Devinn Lanes double-action waterproof toy is a good product for short term use only. Using this on the high speed, for anything more then 30 minutes and it begins to get very hot. You could run a go-card with the motors in this thing, however, burning your special places makes it difficult to enjoy (unless you are interested in that sort of thing).

Also, the title "arouser" is something I would consider misleading as it does not slowly or kindly awaken and stir the senses. This is not a foreplay toy. Stimulation is direct and intense and difficult to control if you are handling the toy by yourself.

It does need to be said however, that being a waterproof toy does make it easy to clean. Especially since it is used for double penetration, it is important to be able to clean the "V" grove of any trace fluids so that bacteria does not cultivate. But because it is so very rigid, I must conclude that the purpose of making it waterproof is for cleaning purposes only - as unless you are a contortionist (congratulations then!), it is very difficult to maneuver in and out, when working solo on the bed, much less the tub! And I've done yoga for years, I am quite flexible, but you honestly have to work too hard to enjoy any sort of home alone, double penetration. I could say a buddy is almost mandatory. Even then you are better off on all fours, rather then on your back or an upright position.

If you are still willing to give it a try, I recommend using a personal massager/clitoral stimulator as well, because while it vibrates like mad, it is difficult to move around as there isn't much of a handle to it. It seems only practical when you use it with a partner, again, it is just too stiff and very little to hang onto in order to use it by yourself.
