Toast 4 I really like the solid construction of this arm bar and clean design. I had to use cardboard shims to account for the gaps between the bar and the back of my fishtank stand. It would be nice if they included some shims because the back of all fishtank stands aren't exactly flush. It was a bit expensive but I understand that is necessary for a quality product. I however have one hole in the 90cm bar that was drilled improperly. The screw doesn't fit in. I'd give 5 stars if I got a perfect 90cm bar.
