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.

After 4 phone calls, mfr, local Sams, Sams main customer service, and Members Mark CS, and a total of 90 minutes on hold, I was informed that a replacement piece would take 10 to 15 business days to receive. Sams will not cannabalize the part from another pkg. As the instructions say, I laid out in my garage, and counted every piece. I then did a physical exam and discovered a bottom pole had the threaded inserts reversed. At 75, there was no way I could reassemble the parts into the cut open box. There should be an expedited shipping of missing or defective parts as part of Sams purchase agreement with a mfr. I am not leaving my car sitting out waiting on a defective pole. I am taking the pieces back without the box for a refund. I will never buy anything from Sams that requires assembly.

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.

I ordered 2 that were pretty easy to assemble, Then I ordered 3 more and they were terrible. The first 2 took 40 minutes to put together with only 1 misalligned corner. The next 3 took 4 hours and had 8 corners that were miswelded and I had to just screw them to the posts. The packing material was beyond terrible and several of the shelves were bent up and had chipped paint. They look good but the build quality is terrible,

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.

The shelving unit appears to be very high quality. I loo forward to using it. However, shipping (via Fedex--say it all) resulted in the bottom shelf being bent. Customer service was responsive! (big positive shout out to Jeremy), but the vendor shipped out the wrong color replacement shelf--chrome instead of graphite. So I ordered this on 9/5. It is now 9/26 and I still do not have a unit that I can use. The month+ turn around to resolve the issue is frankly unacceptable.

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.

I've bought & built 15 of these. Here's how I do it. -Unbox & organize everything. -Find a FLAT piece of floor (not as easy as you might think). -Lay each shelf on the flat floor, rock back & forth, and organize by flatness. -Build from the bottom up. -Put the flattest shelves on the bottom to serve as a good foundation. -Put the slightly tweaked shelves in the middle. -Put the most tweaked shelves on the top. -If you want the shelves evenly spaced, count 12 visible rings between each one. -Put the feet or wheels on last. -If the shelves rock back & forth, use 1-2 washers to shim/level the wheels or feet. We moved last year, since then everything we owned has been "in the basement in a box somewhere", these shelves have been awesome to get stuff organized. I looked around and don't think you can beat these for the money. Hope this helps.

I have 5 of these shelves and they're amazing! Adjustable height is a great feature and I often use S hooks and magnets to hang things off the side. I'm using two in my office, one in the kitchen, and two in my storage shed. They hold up great. Being able to roll it makes it much easier to move to clean it or rearrange. It's just a great product and I rec'd it to a lot of friends and family.
