I replaced a smaller shelf unit from Husky with the same design and this one is MUCH nicer. Notably the brackets that hold the two sections of corner angle together are very sturdy and much better than what came with my other shelf. 4 stars for two reasons: 1. The unit is taller than 72\" as described. My basement is just over 6' tall and I had to cut off about 6 inches of the angle brackets to get it to fit. 2. I don't really trust the quoted weight limit (my heaviest shelf is bowing a bit, and it has maybe 175 lbs on it), but I am not going to push it to it's limit and it works fine for what I need.
