Alternative to Thera-P wrist band?

Back in the day I used a Thera-P wrist band as a kind of maintainer to hold my junk away from my body after hanging or whatever. I don’t think it really accomplished anything, but have lost mine, and would like to find a replacement. Homedics doesn’t make them anymore. When I search on Ebay for magnetic therapy wrist, I see several options, and wondered if anyone has any experience with currently available products that they would recommend or not recommend. The Thera-P was 12 inches long and 2 inches wide. I don’t think the replacement really needs to be that long, but a little wider might be good.
