Impossible to safely secure the top portion to the base. This item is a danger and should be removed from sale. There's no hardware to safely secure it together. I strongly do not recommend.

Thin metal bends easy! The pins will not lock in the holes and rails come loose way to easy. Will be returning these. They are half the price of other brands and 10 th of the quality

I brought it on the one day ale at Sam's got it yesterday and it's not easy to put together and not sturdy enough not heavy at all will not be getting another

I was able to assemble this unit in 30 minutes alone. I purchased 6 of them, got it down to 20 minutes for the last one. Very sturdy for my needs, great value compared to other units available.

This is super easy for installation, space saving, good looking, strong and well organized for your garage. And price is really good if you compare with others.

Used to be a great shelf, I have 3 old ones. Now it is a piece of junk. Just wasted 3 hrs trying to assemble it, does not line up, I can bend posts with one hand !! Now, I will waste another hr to take it back..

These shelves are the worst. Flimsy. Top section is near impossible to get set on the bottom section. I had purchased these thinking they were the sturdy 5-shelf design I had gotten a year ago. I was wrong. I am returning all four.

This product is very difficult to put together....especially by yourself. The shelves are thin and not suitable for heavy garage items. I am returning this product.

I don't know why people are having issues putting the unit together, I did it in 20 minutes by myself with ease. Very strong, sturdy and great value! I wish I bought more as they were sold out a week later.

Recently purchased this unit; having bought six others in past few years. This one now has steel “vertical” thickness of .050; where all previous units steel was .081 thickness. There’s too much “flex”; not as sturdy. Would not buy this again!
