So first off, let me say that the comfort level is great, and the thickness certainly helps the dildo stay nice and sturdy. I will say, however, that the I bought this in the hopes that it would work better than the standard suction cup that came with it. The suction power was okay for maybe the first couple uses, but then rapidly degraded to the point where it had no suction whatsoever. Very disappointing, especially for the price.
I believe this is a defective Knuckle-up product and that maybe it should have been glued together but it separated in the toy. In doing so I could get the tip out of the toy's ac-U-Lock hole with a pair of needle-nose pliers but it damaged the toy (B-10 Warhead) that was just purchased on Jan 30 of this year. I would like a replacement for both the toy and the Knuckle-up both manufactured by Doc Johnson. I have never had this much bad luck with Doc Johnson toys in the past.

This item is poorly designed and has a weak suction cup. The hinged portion stopped holding it in place after one use. waste of money.
