Yes, I have (got the concept and a "simple" one) I turned to Goethals (carrara) because it was convenient at that time (was living in Belgium) to go there and get a belt manufactured. I kinda regret…a lot.
Listen, it's not like the belts aren’t any good at all, but there’s certainly a lot better out there. Think twice.
As far as security is concerned and certainly as far as quality is concerned. The belt is terribly heavy, if you don't have a back in reinforced concrete you're in for a unpleasant surprise after a few hours, let alone days of wearing. Goethals uses hinges. You have to keep them greased or they start making squeaky noises at worst, at best (no grease will help for this problem) they will make clicking noises after a few months of wear-n-tear. If you like to see people's head turning in wonder when you're walking by ;-)
At the hinges after a few months of wear the lining will tear perfect recipe to get your skin pinched afterwards...not to mention the really painful pinching of any tenth of a mm of skin of your ball sack that will peek through the small openings of the cage holding the testicles...
The tube is (was?) formed out of several parts welded together to form an arc and painted on the inside. After a few months the paint comes off and you'll get bruising from the +/- 5 to 6 welded parts that make up the tube.
And I could go on some...
Since I went personally to Germany (Neosteel) I so do regret that I spent money on the two carrara's, I could have been in chastity belt heaven ages ago.
