The good and the bad
Your review: The upright support poles are heavy and I really liked the inch markers. However, the plastic pegs to keep shelves in place very MUCH more difficult to use than other brands. It took 2 of us to get each shelf seated properly as the plastic stops kept slipping.
Pros: I like the weight, I feel that it will support the boxes that need to be placed on it.
Cons: Again, those plastic stop clips just did stay in place and it took a lot of effort to get the shelves placed properly.
