The Eden Vibrating Masturbator design has a few flaws from my own female perspective. For example, it's slightly curved, which great if you're using this solo and have big triceps, but the curvy design and the placement of the buttons for the vibration are something I fumble through a little when I am the one operating the machine. That being said, if you are going to use this as a truly "handsfree" option, the curve is perfectly well thought out and actually serves as a benefit. Also, if you plan on using this masturbator as "handsfree" the controls are very conveniently located. As a whole, the design is well thought out for the purpose of the toy, but causes a little trouble when you don't have it mounted to the wall or a desk.
I really love that Eden thought out putting in an interchangeable bottom. There's the suction bottom (for hands free use) as well as a small little cap for when you're using it manually. The little downfall here is that no matter how tightly you seal the bottom, a small amount of water can get into the battery compartment. That being said, it's a VERY small amount of water. If you take the extra step of removing the bottom and checking the compartment after cleaning, you won't have too much of a problem. My personal suggestion is to remove the batteries during cleaning, put the lid back on the bottom, and then proceed as usual.
The suction cup works pretty stinking well. It stays on different surfaces, such as shower walls, desks, and glass tops. It also sports a push button that allows you to change the angle that the toy sits at, TOTAL BONUS.
The lid that covers the portion that holds the sleeve is a twist on. It stays on excellently. The small piece of plastic under the lid that holds the sleeve in place (it's silver) pops off a little too easily with aggressive stroking. We super glued ours, let it dry for three days, and haven't had a problem!
The toy, with the the suction bottom and lid on, measures a whopping 13 inches. The things is giant! The removable sleeve, however, is a tiny six inches. My man touches the back of the toy during use, but it doesn't bother him too badly. If you are ridiculously impressive down there, you might want to steer clear of this one because you will find it a little small.
The vibration feature of this toy makes it a home run. Read about the Functions and Controls to learn about that.
