I've read a lot of reviews saying they aren't very durable but I haven't come across it at all. There are so many adjusting nuts that I think it could just be bad batches or user error, but they were very easy to install, very easy to attach monitors to, and they came with everything you need. Make sure your monitor is VESA compliant and you're spot on. My only wish is that the cable management is better - it looks a bit messy but it is what it is.
