I decided to try these shelves recently because the Gorilla Racks have been out of stock at Amazon for over a year now and because of the positive reviews given here. BIG MISTAKE!... The planks and steel used on this rack are WAY thinner than those of shelves easily available at at convenience stores for the same price or lower, and it does not seem to be sturdy at all - the bars bent easily with soft strikes of the mallet. Luckily, the material was malleable enough for me to hammer the bars back into shape. Overall, the quality of this rack is CHEAP and definitely not worth the $140 it sells for. I would have returned it for a refund if I didn't want the trouble of having to put all the pieces back in the box and transporting it to a shipping station.This is a good product. I had to return it though because the items and tools I needed it for were too heavy. This company was totally cool about my refund. They were very professional in working with me on my return. The only reason I gave it four stars is because I had to return it.I need one to organize my things. I'm very satisfied with this item. Very easy to assemble, I did it by myself. Very recommend.I needed some garage shelving to store various power tools, gardening stuff, paint, etc.. I purchased 2 of these units and realized I could use 1 more. I also purchased another rack for a different section fo the garage to hold sports gear and the like and wanted to check out another unit.I planned to write a review outlining the little tricks and tips I learned setting up two units back to back, but in reality.... you should just buy this instead "Muscle Rack UR184872-R 5-Shelf Steel Shelving Unit, 48" Width x 72" Height x 18" Length, Red".If your time has any value at all, its worth the slight premium. Not only does the Muscle Rack set up almost instantaneously compared to carefully aligning the tabs on this unit, it is significantly more sturdy when loaded up (now with tools and heavy stuff like I planned for these). The major difference in construction is the gauge of metal (if this one is considered Heavy Duty, god help anyone who gets something lesser) and the flimsy bendable tabs to lock things together vs. the Muscle Rack's circular drop in tabs. Do not buy a unit that has this tab style fastener system like this one. On the first unit maybe 2/3 of the tabs didn't slide into the second sleeve the first time, round 2 maybe 1/2 the time. I still have not received the 3rd rack, though it was ordered same time as the Muscle Rack.Edit: Dropped a star since the Muscle Racks in now only like $3 more. Do not buy any rack with the folding, slide in tabs. Circular drop in connectors are the way to go (thought now i'm sure there will be super thin gauge drop in connectors that shear off that will negate this advice).The materials for this unit seemed very off.... I built it and added all of my items to it and it works great! I do not like that the brackets/tabs used to assemble sometime pop out, it was hard to keep them all tucked in like they should be, but overall this is a great unit! I'll see if I can get some pictures of where I am talking about, but as of now, it is filled to the brim, and holding strong!It did take two of us but after we figured out they went together it could have just been one. They are super easy and fast to put together. Took us like 30mins for 2 of them. I use them in my garage to hold tubs mostly and they are awesome! Love the color and they are sturdy. I didn't mount them to the wall but they aren't somewhere that kids or anyone could pull them down or I would have. They provided a few extra items to make sure we were covered and would easily order more if I needed more. Great price and great product. I'll try and get some pictures up when that feature is back online.
