Comfortable, adjustable, no issues. Durability and quality are good relative to the cost. (I've bought them again).

Overall, I can't say that I mishandle them.
The only "bad" thing I did to them is that sometimes, instead of wearing them properly, when I sit down I rest my feet on them, meaning I step on the part with the Velcro.
The result is that within a year, the plastic either breaks on the left or right side.
This is what happened with the first pair I bought and now with the second one.
If you "respect" them more than I do, they will probably last longer and you won't have any complaints.
But for me, they just don't work in the end.
