Bending and flying away when got some pressure
After two months of usage the connection points are bending and flying away when you sit. I bought this by thinking Amazon is the seller but it is not different from the ones cheap fakes

Just pops off the rails immediately
This worked for about a day, but since then it's been unusable as the clips don't hold it on to the rail. When I lean back it just pops off and falls on the floor.
