There are far better ones out there...
I love the idea of this, but the reality didn't quite pan out. The screw-on dildo is a great idea from a stability standpoint, but it's a little hard to use. The base--and the dildo--are very stiff and it's hard to get in a spot where it's comfortable, at least for me. And because it's such a stiff material, you lose any sensation. We tried it twice and then just made a trip to the store to buy a better one. My advice: skip this one and go with a o-ring one. You'll get far more pleasure and you can change the sizes to suit you. This one turned out to be a bit small for us, too.
