Ballstretcher - Hodengewichte 

Great weight, snug fit

I received my size “small” earlier this week but, being relatively new to stretching, had warm up to getting the device on (a quick jerk and warm shower helped). The magnets are pretty strong, so the risk of pinching is real, but once you’re able to get it on, the weight feels great and the device is comfortable. Personally, I’ve worn it now twice, in 2 or 3 hour increments, and look forward to more. One note: it’s not water-safe (alcohol clean only), and the only criticism I have is that the edges on the inside (when the magnet joins) could be eased a bit more to reduce the risk of pinch.

That said, I love it and plan to work up to the next size in due time. Cheers!
