Works fine but does have its issues.First thing to know, is not as "beefy" as you might think. Each loop bar is only half an inch thick, which does help and allows for room when putting it all on. It's also not a tall ad you might think, only about 5" top to bottom.It DOES NOT come with assembly instructions. So, i had to go back to the product images to see how it was put together, unfortunately, in my opinion, the images are not correct. You'll need to put both metal screw nuts together (one on top of the other) in between the two stretcher loop bars. Otherwise the bottom loop bar can move and "float" upward. Neither the loops nor the base plate are threaded. To spread the loop bars apart, one nut gets screwed upward and the other below it gets screwed downward. The nuts are 10mm in size.The base plate would be better if it were slightly wider front to back. I'm somewhat larger and found out, as you tighten, you can get some body movement backward or forward on the bottom plate. Which means, you won't get even pressure or an even crush.I was initially concerned there might be some on and off metal pinching or edge irritation due to the loop bars design on how they join together, but once screwed together there were no secondary issues.Over all, it's a nice item and I'd recommend it.
