My first gripe is that it is in 3 separate sections, not just one. Obvs I can join them but that takes a little effort and uses up some of the connections.
My second gripe is that it has an odd fitting. It is bolted onto a backboard and has a second stud that requires a hole, so that one bolt is enough to hold it firmly. That's fine but the dimensions and positions of the holes are all weird. Usually these things are a round number of mm or inches, but not in this case. This makes fitting a little harder. Also, the two holes are not symmetrical, so if you drill your holes from the rear of the board you must remember to reverse everything.
Given these minor design complaints, I will finish by saying that it seems to be well made (haven't used it yet) and it was the best thing I could find.
