Robo suck - penis pump by Doc Johnson - review by BigBadMrWolf

The use of this toy is rather straight forward. You insert your member into the inner sleeve, and turn up the power. The toy, in theory, does the rest. Obviously, this toy is limited to the male anatomy. The nature of this toy, in my opinion, doesn't really lend much to couples play, either. Thus, this toy is probably best suited for solo play, in a non-aquatic environment -- due to the non-sealed electronics.

The packaging states that the product is made of PVC and Phthalate Free ABS. There are also unlisted materials, such as metal and other plastics, which may or may not be ABS. I am assuming that all parts that are in contact with skin are composed of the listed materials. I am disappointed by the material that's used to make the outer cylinder; it seems rather low-grade for a toy, and it really reminds me of cylindrical packaging that I've seen on a few dildos. This toy also requires 4 C batteries, which are not included.

I'd caution those with thicker members to think twice; I have an above large member, and I barely fit into the inner sleeve. The design isn't exactly pretty... I'll call it manly, which is probably a good thing since the market is for those with penises. It doesn't look nearly as nice as the product featured in the pictures on the packaging. The part that does the 'sucking' can move up and down the cylinder with a little effort, so you can adjust where the sensation occurs. The surface area of the part that actually does the stimulating is quite small. In total, it only moves about half an inch along the member, so only a very small portion of the member is being stimulated.

The toy is controlled by a wheel on the battery pack, which takes approximately a half turn from off to max power. This is definitely the loudest toy in my collection; it sounds like a squeaky motor turning back and forth.

This toy has exposed electronics, so great care should be used in cleaning. The inner sleeve can be removed, and I would suggest fully removing and only cleaning this part. Other parts of the toy can be spot cleaned as needed, but they shouldn't require too much maintenance. As with all toys that require batteries, I suggest storing without batteries -- especially on toys that are as easy to turn on as this one.

This toy sucked at sucking; I could hardly feel anything. I was also not thrilled by the requirement of 4 C batteries. I had to go to three stores to even find C cell batteries.
