Product Type: Blowjob Type Onahole
If you're considering this then just get "The Mouth of Truth Perorin (La Bocca della Verita)" or the "Nodo Oku Deep Throat".
This thing doesn't even hold a candle to those.
-It's good at convenience (but it's not much smaller than much better holes)
-You will fall into this, the ridges that hold it in place in the cup dislodge too easily
-The suction feature it a good idea but it's just that the ridges ruin it. You literally pull it out with the suction so you're not actually able to enjoy it.
I've purchased this item a couple months ago and I can definitely say I am well satisfied with this product. The sleeve itself comes in a cup with a hole on the top in which you can cover with your finger to add to suction. I've been constantly using this item about two or three times a week and still shows no sign of wear or tear. It seems like it can handle some rough handling itself as well. It's also very easy to wash as it flips inside out easily. Overall, I highly recommend the product!
