Double Sided Suction Cup II

I bought this to use with the Andromeda dildo, the base is about the right size as the medium suction cup had too much overlap to stick. It sticks on pretty easily with a careful line up and slap and then whack it on the tiles and you're good to go.

The problem I found at least with our tiles is that it slips down during use and once on the joint, just falls off, sometimes even coming off without being touched - you inevitably then get lube on it as you're trying to stick it back on which makes it less grippy so have to keep stopping your action to clean it. I ended up switching to a dildo with a bigger base so there was no lip but even that came off when using it at an angle (as is inevitable when using a longer dildo and the human body!) unless you can line up perfectly to push it directly into you and onto the wall like o------| -> o-|

That said perhaps the tiles just aren't great, I've used the bigger cup on a set of drawers on all fours without much issue

Well made and very effective, can't fault it for performance, once it's stuck it's stuck! Went for a small, which is the ideal companion to a collection of Sinnovator medium size toys.

I use these in a lot of ways. Often as an additional stabilizer with a strap on a flat plate adapter on a machine. The suction cups are very strong and well designed. The smaller diameter allows toys that may have over sized suction cups molded into the base to still be attached to surfaces that can't support that large of suction cup.
Worth every penny, and it has really improved the function of a number of toys in my collection.

Got this in today and tested at work on a fridge as the office was empty, held up the Stallion in large with no issues and came off easily enough. Tested at home on tiles, slap it on, bung the dildo on, enjoy. I bought it in large, the base for my toys will fit inside it but even the Stallion with a little lop in the base was secured, I will test it more later in action but I can't see any fault with it. I recommend measuring the base, a smaller one might be better for inside the base of some toys

Very handy , can use it with most of my sinnovator articles
