It only took me about 25 minutes to assemble this rack. Half that time was spent just unwrapping the pieces. The pieces were wrapped quite well. I was also impressed with the quality of the powder coating. Surfaces were well covered and the color and texture (slightly rough coat, not smooth or shiny) were great. If you follow the well-written instructions, they don't tell you to put on the wall attachment clips before you connect the top piece to the rest of the frame... If you plan to screw it to your wall, you'll save some time if you remember this small omission. Otherwise the assembly instructions were straightforward. I really like the way this rack doesn't need to be mounted to the wall. It's very easy to set the height of the arms for the two bikes, put the first one on the bottom and the second on top. I had some worries about whether it would remain stable if I took the bottom bike off and left the top one, but, no issues so far. You do need to be careful to lift the bikes slightly to clear the frame hooks, but, this is pretty obvious and if you start to do it wrong, the whole rack will let you know pretty quick. Overall I'd give this a 4.75, if I could, but Amazon only allows whole stars :-) It's a good space-saver in my garage.
