The Vac-U-Max turned up okay (it was posted from the USA to me in the UK). The Customs declaration on the padded envelope had 'child's toy' written in the Item Description line, which amused me and my wife. In the packet was an instruction sheet, a soft silicone penis gripper (kind of like a short thick condom) with a snap hook/fastener on it's tip. There's also a black elastic adjustable leg
strap and a lighter adjustable elastic to go between the penis gripper and the leg
strap. To put the thing on you have to roll up the penis gripper (just like a regular condom is rolled up in the packet). This is aided by ribs inside the gripper which help it to stay rolled back. You place the tip of your glans in the gripper and then roll it on, where it grips the glans and part of the shaft. Then you fit and adjust the
strap and that's it.
The instructions say to wear it for only short (45 minute) periods to start with. Before it arrived I was a bit skeptical about it's ability to stay on, but it's very secure. If anything, I wonder if it possibly has too tight a grip for me, as I have found that after wearing it for a couple of hours at at time, my glans has a couple of slightly pale patches which feel a little numb, making me think circulation had been restricted. It could be that I wore it for a bit too long too soon (I've only had the thing two days), so I'm taking it a bit easier until my cock gets used to it.
All in all, I think it has the potential to be a good stretching device, but I won't be certain of that until I am able to wear the thing for longer periods. My reservation at the moment is based upon my worries that it might be too tight for me. I'll keep trying with the thing for a week or two, and I'll post an update here.
The silicone is very soft and pliable, but I reckon that guy's with larger than average glans might have difficulty with this. I'm combining this with my usual pe routine, so my glans is temporarily enlarged due to jelking each morning. It's possible that the gripper would fit me fine if I wasn't doing the other pe. I'm thinking that if I continue to have problems with tightness, I'll ask the supplier if the makers have plans for grippers in other sizes.
