The Calexotics The Gripper Spiral Grip Purple is a heavy-duty, open-sleeve masturbator designed to please. The open-sleeve design allows for a grip as tight as you want it. Squeeze it tight, or loosen your grip, this masturbation session can be anything what you want it to be.
I (30's M) chose this first over a sheath/tube style toy as I figured the purported ability to "grip" would be handy. Wow. Was I wrong. Immediate first try and my penis barely stayed in the "bun". By barely I meant it didn't. I don't have a weak grip at all but add in (absolutely necessary) lube and the grip was awkward and unwieldy no matter which way I tried to grip the gripper. Terrible design.
Frankly, I don't know who this product is meant for as it was a complete disappointment. Probably a reason why you don't see this style in skin flicks despite it showing more skin: there's just no way to keep a penis in. Plenty of sheath/tube style toys are far better options than this. I ordered a 2nd, cheaper sheath style one at the same time (on a total whim!) and it was completely satisfying compared to this would-be sex toy and waste of money and materials.
Would star this 0 if possible. Avoid.
