I Have that device. lol. As well as the anaconda and I think the python. The last two are extremely difficult to stay tight enough to do any good given how they designed it with the pullable straps. Perhaps, on a non filled cock though, that can be strangled so tight that it engorges the glans, it would be better; I cant say. I have done this type of strangulation before with some homemade stuff, and that type of forced engorgement starts to hurt eventually ( not very long ) and things have to be adjusted.
As for the device you mentioned. It really is a nice theory and concept for keeping the penis weighted. For me personally, I had A LOOOTTTT of skin pinching between the rings. I do think this device can work for some though, with some trail and error for comfort and settings. Just not for me. I also have their power grip. I like it the most of the products I have of theirs, as it is very similar to a weight that I built and use in the same location. Once you are filled or other wise very girthy, this product is hard as fuck to get down to the base, ANND THEN, after you are swelled, up after a length of use, ( which happens BTW with wearable weights) you have to really squeeze and compress the dick for a while to get down to a size to get it off. - Im not knocking it by saying all this, Im just pointing out the flaws that they don't, lol.
Before this product ever came out, I was making homemade wearable weights from steel, In larger pieces. Then i switched to tungsten for more weight and smaller surface area. I ended liking these types of weighs more than all others personally. They left room swelling. Some guys in here can vouch for all that I am saying as they have got in on some orders with me over the years for my stuff. I just never got around to bringing these to market. \
Hope this helps you some. There is no right or wrong product for everyone sadly. There is only spending a lot of money to try different shit until you get something that you like and that works for you. Thats why I started to build shit, lol.
