Versatility
I’ve been using the airclamp for about three weeks. Prior to that I was using the sleeve/cable clamp combination mentioned above.
I always found the cable clamp to be fiddly - especially if there’s any lube involved - and quite unforgiving of mistakes.
Using the airclamp is a much gentler process but when it comes to getting the job done - creating expansion - it is at least equal to, and perhaps superior to the cable clamp.
I’ve followed the instructions as outlined by sta-cool above but would add a little more detail from experience.
When putting the clamp on, pull your dick out to allow wrapping as close to the base as possible. I go past the hairline to include some fat pad. After doing the first pump I then use the wrap to jelq, along with some kegels and continue pressing the wrap into the fat pad as I expand into it. To jelq with the wrap I just use the forefinger and thumb of each hand to push the wrap up along the CC. Once I have enough of an erection I’ll pull down on the wrap to press it all the way into the fat pad, kegel, hold, and pump one more time to lock it in. Once that’s done I’ve found that it won’t move back up toward the shaft.
I’ve found this will maintain the engorgement (mine is about 1 centimeter) for a full set of 10 minutes or so. This is the same as with a single cable clamp - though it’s more inclined to subside with the cable clamp. I can get more engorgement with a double cable clamp but I’ve found that to be a risk not outweighed by appreciable benefit at the moment.
Where the versatility comes in is being able to release, pump once, and start the jelq/kegel part again. Additionally there are an infinite number of levels of squeeze that can be applied. However, I’ve found more than one to put an undue amount of strain on the base without any sizable increase in engorgement.
As to gains, it’s too early to tell. But if a cable clamp creates gains the airclamp must also, simply due to its ability to create and (more efficiently) trap the engorgement.
I hope this is useful.
