On average, 1-2 shelves in each box has a won't fit well on all 4 corners. It's because the welding connecting the shelves to the cylindrical sleeves that go around the pole is of spotty quality. The welded material sometimes jets out into where the pole should be - either preventing the shelf from going on the pole, or making one of the corners not fit evenly. In a couple cases, there was a corner with the cylinder not fully closed, making it too loose to hug the connectors. Also, please read the description / packaging carefully​: the allowed load is GREATLY reduced if wheels are used instead of the stationary feet.

Very sturdy and well built, i was amazed by how much it held and how quickly it organized so many things for me. The wheel are great if you need to paint the wall behind it or move it for any other reason. The only thing I thought might have been a tiny bit better was the instructions on the little black sleeves that go around the poles. The instructions say it will "snap" togeather. Well, sort of but if your like me and keep waiting for a "click" noise you probably won't. But they are great shelves, buy with confidence!

You can go buy a plastic shelf at other stores for $49-$69 which can hold a couple hundred pounds. This thing can hold 800 pounds with the wheels installed or 6,000 pounds, that 3 TONS, without the wheels. I couldn't make a set of shelves out of wood, that could hold that much for under $100!

Bought this item "NEW", when received, this item was an obvious returned item, several small parts were bent and broken. I wanted to return it. Thank goodness my husband was able to put it together with misc. parts he has in his workshop. Shame on you for charging us full price for a return.

Not sure why the Members Mark shelving requires a small threaded connection, most of the others don't. Mine was likely a return, and had been cannabalized. Opened box, missing parts, even extra parts. I will say that working through the system, I was able to receive correct connections, rare.

The only reason I gave this 4 instead of 5 stars...one shelf was bent when I received it. This wasn't due to shipping damage. The bend shelf was in the middle of the packaging. I was able to support it on the garage floor with a 2x4 and apply some of momma's good old collected cooking (my body weight) and with some carefully applied pressure, you can't really tell it was bent, unless you look really close. Other than that, these are well made, heavy duty and come with the option to use the supplied wheel kit or leveling feet.

We now have seven of these shelving units in our basement. Manufacturer needs to improve packaging to protect the six thin plastic shelf liners from damage during shipping/handling of a two-person lift very heavy cardboard carton. Three of the six shelf liners are damaged as 3"x1" sections of the shelf liners were "sheared off" from the sides of the 48"x18" shelf liners. I am asking Sam's Club to help me work with the manufacturer who has a burdensome warranty policy/procedure that includes returning damaged goods at my expense. All I want are three new replacement shelf liners rolled up and protected with bubble wrap on both ends in a cubic box before being shipped to me.

I got about a dozen of these for our warehouse and shop and they are perfect. They are built well, very sturdy (and heavy) and easy to assemble. We are about 45 miles from the nearest Sams Club and they were about $99 there, I had them deliver them instead of me using my gas $$ not to mention they are HEAVY and they only came to about $102 including the shipping - great deal!! And the carrier brought them in and everything, all we had to do was cut open the boxes and assemble. As for the quality, they are surprisingly sturdy and heavyweight. We also own a restaurant and they are much better quality than most of the ones we can get through restaurant supply and about 1/2 the price. I would definitely recommend these to anyone whose needs fall within the weight guidelines.

Ok. I'm a pack rat and I'm cheap. I prefer to be called thrifty but when we moved into out new house with a huge basement, I needed some way to store all of my stuff. These storage units were perfect. They're incredibly sturdy and if they can't hold it then I probably couldn't lift it onto the shelf. Assembly is easy but takes some time- I bought 14 of these units. They roll easily and look great. Look no further for your storage solution.

This is the nicest and largest for the price that I've seen. I ordered one and was so pleased that I replaced another shelving unit I had with another one of these. These are taller and wider than any I had so the shelves hold so much more. The only thing I don't care for is the plastic pieces that cover the shelves. If you had cans or items that would fall through the wires then the plastic pieces would be good but every time I place something heavy on these, it pushes the plastic pieces out of the way.
