Since this is the one I use too, here some comments
The quality surprised me, it's very good. Very secure too, I'm impressed. It must be very tight on the body of course, but definitively works
I have made a lot of changes:
- The lock must be changed, agree... it's really flimsy
- I changed the cover of the cable with tubes made from medical silicone. It's not bad, but this way is much more comfortable and larger, so less pressure
- I covered some metal parts with electrical tape. Not the best solution, but a good one. I change it every week
Another thing is that I retake the measures 11 times!
Overall it's fit for its purpose, which is preventing wandering fingers and keeping her inside it. On the other side, I have some doubts about using a rigid belt, the cable one seems much better on comfort side, but I have no experience with other belts, it's just an idea.
