Shelves are not welded closed properly, meaning they will slide down past the plastic markers used to hold it up. Obviously not how it's supposed to work. Sam's Club Customer Service was no help either. The shelf weighs over 50lbs, but online support wants you to pack it up and bring it all the way back to your nearest club, rather than just replacing the defective part. Heck, even a partial refund for the defective shelf part would've been a better option. Someone's going to put a lot of weight on this shelf and it's going to either snap, crush or otherwise pin something when the shelf doesn't hold.

Excelente product

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.

We had this shelving unit in our garage. Our home was leveled in the May 20th tornado in Moore. The shelves were found, all in tact, wheels and all. We were impressed that it survived a disaster that destroyed our home and still in great condition....that speaks volumes for this brand and sturdiness.

After helping my mom assemble one of these, I went immediately out and bought two of the standard and one of the corner. I used them for a complete garage re-org. All are extremely high quality and easily support heavy things such as my husbands many tools, saws, and car parts. We used the wheels and just braked them in place.

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

The box arrived damaged, completely torn open on one side so I was concerned there might be missing parts. Luckily, this wasn't the case. The rack is very strong and sturdy and I'm very pleased. Although assembly requires no tools, I found it a pain. Possibly, it would have been easier with 2 people. The clips that attach to the poles kept snapping off when the shelf was placed upon them. I ended up using a bit of strapping tape to keep them together. Once the shelves were on, the tape wasn't noticeable. An alternative to these plastic pieces might be a better idea, but overall, it's an excellent product.

Only advice I have to give 1- Have some help to put this thing together.....LOL 2- It says use a mallet to seat the shelf, go easy. It will bend. I fought this thing putting it together. Along with a need little dog that was in the way 99.9% of the time. I had lost a plastic piece that goes in the holes on the corner of the shelves. Two each for every corner for a total of 8 per shelf. So how did one completely disappear??? Looks like my little friend took off with it and chewed it up some, found it in the other room when I went to take a break. With that said, there is extra pieces. Nice thinking on the manufacturers end. Only negative I seen is when you slide the each shelf down the legs, it peels the protective plastic coating on the legs. Not that big of a deal, you really have to look at it to see it. All nicely packed in the box, no damage. If I need more, I will purchase more from Sam's Club.

These shelves are the best. They even have shelf liners so small things sit sturdy. The convince of the rollers makes cleaning a breeze. They are just the right depth for most things. You can adjust the shelves within a few inches of your need. I left a shelf out of one unit and add it to another where I needed.

These shelves are the absolute best! I've used them all around the house. I got rid of those rickety ol' plastic shelves that bow from weight in my garage and replaced with these. The casters are heavy duty and allow me to easily move the shelving unit out when something falls behind them or to clean underneath [shhhh....don't tell the wife cause she believes I don't know how to clean]. They come with pretty thick plastic liners to put on each shelf making it real easy to clean up any spills as well as prevent material from falling through onto everything underneath. The shelves are easily adjustable to accomadate any height product I choose to put on them. They are also great for putting books on since they never bow like most wooden bookcases. I got one for my daughter's closet to put all of her sweaters, shirts, sweatshirts, towels, and bed sheets on and she loves the way they organize everything. I found the assembly easy and I do mean easy! No tools required. Once you learn the nack of looking for the double notches on each pole, it's easy to line up the shelf height prior to sliding the shelf over the poles. I can put a whole unit together in under 15 minutes while drinking a cup of coffee in the other hand! Well, maybe not at the same time. I've even made sides out of white masonite and 3/4" x 3" white pine to make an enclosed unit. A couple units I put pegboard ends on to hang my gardening tools from. I offered to do a setup for the wife's cooking utensils but she thought I was being rediculous. I just wanted her to use the cooking utensils instead of using her favorite recipe book...the Yellow Pages! And that's how the fight started.... You just can't go wrong for the price given the quality and versatility of this unit. None of the units in the garage have corroded. They all stand up to any abuse I've given them.
