Something like that lends itself to a 3D printer. Any geeks here able to replicate something along those lines?
Looks like a clone of a CB6000. Plenty of them around. They are comfy but bulking and a pain to put on and take off. I had one but it was not durable enough for 24/7 wear. Broke the ring twice in under a year. Holy Trainer V2 is much more comfortable and flexible. That is the best off the shelf one I used out of 4 that I bought. Ultimate comfort was only achieved with a custom made Jailbird by Mature Metal. I actually have worn one for almost 4 years, every day. Most guy do not have the need to wear it for years and in that case, a Holy Trainer V2 is a good choice.
Definitely a Reinholds. One of the first devices my now ex and I thought about getting. Much cheaper than a latowski back then, though at the time she really fancied having me long term in one of those and we were only at the talking about trying a device stage.
