I bought one of these several years ago. Then I decided one was not nearly enough. I think I have purchased at least seven of these over the years and truth be told I would love to order at least two more. The quality is excellent. I would not want to try it but I bet you could exceed the 600 pound limit on these. I like the fact that I can roll them around easily. I have some of these in my garage and if I need to make space for a project I just roll these out of the way. the wheels are lockable which is another thing I like about these. Sam's has an excellent price on these. I've seen shelves similar to these elsewhere but lower in quality and much higher in price. Honestly I do not see how sam's can sell these at the price they do.

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!

I have purchased 8 of these exact shelves and am very satisfied. Out of the eight one did have a bent shelf that was quickly replaced by manufacturer. I have read the negative comments and mostly it seems people don't know how to assemble or assume the plastic seperators used to protect shelves in shipping are actual parts. When you put the poles together sometimes they are not a perfect straight line when combined but once you put the shelves all on the unit is straight every time. The fact that these have plastic shelf liners makes them a fantastic value. If you were to purchase seperately you would spend $40 or more for the shelf liners.I am extremely pleased with these and will probably buy another 6 to 8 units over time.

When I got package it looked like it had been to war. It had been opened and repacked. If your going to sell a repack give a discount.Had a bunch of plastic pieces in the box which I don't use anyway. It went together allright. The main thing was it being opened.

We have about 40 of these racks. We just got a few more in and the notches for the plastic stoppers to fit in are so shallow the plastic guides slip right down. The old ones were manufacturered in China and these are made in Vietnam. There is no way the shelves will hold the weight they are advertised to. DO NOT BUY THESE

Bought one of these to make two carts to use in my office. Bought one extra set of casters, put three shelves on each cart, now I have two carts with 3 shelves each, and it's great. Definitely a well-made and heavy-duty item that will last for a lifetime. Relatively easy to put together even for an old lady like me.

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.

The unit is very sturdy and fairly easy to assemble, take two people to install shelves. The only disappointing thing is one of the shelves was bent and won't fit correctly. I just put it together today and haven't contacted anyone yet about bent shelf.

Bought three sets; many of the shelves have not been buffed properly (sharp edges pose imminent puncture/injury risks). I punctured my fingers of my right hand twice leading to bleeding and had to file down the sharp cutting edges. No other complaints besides the real risk of cutting and injuring oneself.

First shipment. Box was severely damaged with rips and holes. Broken plastic pieces fell out of the hole while carrying it to the garage. Sent back for replacement. 2nd shipment i received someone elses return. Package was already opened and taped up. They couldnt repackage it so that thr top box flaps will close all the way.
