These things will give you an ultra stiff limb. I have no trouble getting hard in the first place, but these things will get them veins popping to the max. Not only that, but I last longer and "finish" harder than a donkey kick. My wife enjoys me wearing these too. I'm a big fan.
Its hard to say much about these due to the fact I got these as a trial for my husband, but he really wasn't into them.
Not stretchy enough that you don't get some soreness afterwards.
This set was kind of a letdown for me. The silicone used for these seemed more like the commercial type used for seal rings and gasket materials.The elasticity was - well, not very giving. Pretty sure I would have damaged some goods if I had tried to, uhm, install and did an Oops while doing so. (Ouuuch!) Although I have had better luck with (another brand of) silicone rings this one was just a little stiff for my use. Would likely work great for someone.
i used all of them and they felt great...well received!!
