Some interesting points about this item: 1. Easy to install. Best if you have a rubber mallot to tap shelves into place. 2. This unit assembles as a single 6 shelf unit on wheels or on adjustable feet. 3. This unit can be assembled as two 3 shelf units - one on casters/wheels the other on adjustable feet. 4. the unit on casters has a total limit of 500 lbs or 3600 lbs if not using the wheels. I am not sure if this is a missprint or not. But what is interesting is that you can morph this unit into what suits you best. For me I have a single 4 shelf unit on casters. No tools required, but a rubber mallot is helpful. A regular hammer might chip the finish.

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

Very sturdy and great capacity. I did not use the wheels but the leveling feet it was very easy to adjust and make stable. Assembly was a challenge for one person, too many parts. A measuring tape was helpful to get the shelves level. Have a plan as to what you want to store on each shelf; they are difficult to move once the unit is assembled. Highly Recommend!

This rack is super sturdy and the casters make it really great for garage storage. Didn't know that there were plastic inserts included for the shelves (so things don't slip through). What a nice surprise! We've generally put plywood down on other ones. Was great to set it up and load it up... Would highly recommend this unit! But don't buy them all, we may need a few more ;-)

This is the third or fourth rolling rack shelf we have purchased for business and home. Each time we put it together was a bit of a struggle but overall they are super sturdy and work great. The wheels are great where lock in place as well and are very sturdy. Overall it is a great purchase.

I bought three of these to make 2 units with 9 shelves each. I bought them to store specific items -- DVD/CD boxes that hold literally thousands of back-up and home-made DVDs and CDs -- after searching what seemed like FOREVER to find something suitable that didn't cost a fortune. (I was actually considering having a carpenter build me custom shelving, but that would have cost close to $2,000!# I took a chance on these because they were inexpensive and I knew I could use them in my garage if it turned out they didn't work for the DVD boxes. Well, they work GREAT! #See photo!# The only negatives, and they are minor, is that assembly of the first one was a bit of a pain. The instructions tell you to screw together the poles that form the frame, then screw in the wheels, then put on the shelves. The problem is, if you are assembling these yourself -- no helper! -- this won't work, as it will be almost impossible to get the shelves over the very high poles with the legs wobbling all over. #You can lock two of the legs, but that wouldn't help much -- the first shelf is the hardest to get on as the poles of course are not really a "frame" until something is on them!) After following instructions, I realized that wouldn't work, so I took off the wheels and separated the 4 full-length poles into 8 half-poles (as they come). THEN I was able to get the first shelf on over the plastic clips, and then the second, etc. After I had four shelves on, the unit was quite stable, and I was able to screw in the 4 half-poles to make the top half. I added the rest of the shelves, THEN propped the whole thing against my basement wall to put on the wheels, one side at a time. It wobbled a bit when I was putting the 3rd and 4th wheels on, but it wasn't really an issue as the unit was VERY stable with all the shelves. I had no problem with the plastic clips -- once they "click" into the line where you want them (I just counted lines to make sure they were even), they held fast as I loaded the shelves. One tip for assembly: don't assemble them until you are sure what you will store on them. Yes, you can disassemble and reassemble them, but that won't be too fun -- better to know what you will be storing at the start and plan your shelves accordingly. Taking 15 or 20 minutes to plan first will likely save you a lot of aggravation later. And one last thing. These units come with 6 shelves PLUS the shelf liners, which a lot of the units don't come with if you buy them elsewhere. I didn't really NEED the liners for my purposes, but they are nice to have for the future if my needs change. Overall, a GREAT purchase at an amazing price. I plan to buy the corner unit and some more of these as well for my garage. I am so impressed with them!

I love this shelf and would’ve given it five stars, it is the second one I have purchased from Sam’s. The delivery was terrible. The box had been opened and re-taped. Obviously someone had purchased and returned it, because several of the parts were out of their plastic sleeves, and all of the zip ties had already been cut. The box broke open when it was placed on my front porch and pieces fell out.

These came highly recommended by a friend, and I really like them, too. I found them difficult to put together--it's awkward to get started, the instructions are not clear, and I think the first one I put together is not as solid as it could be. But the second one was much easier and faster, and it is very solid. (Hints: It's easier to put the casters/wheels on AFTER it's assembled, contrary to the written instructions. Otherwise it just rolls around while you put it together. And make sure the locking plastic clips are really together and snug in place before adding the shelves. You WILL want to use a rubber mallet....) I really like that I can roll it around easily, which means I can line them out and pull one out as I need to access it. For the money, these are handsome, solid units, and I recommend them.

I have purchased 6 of these racks. I use them everyday, and move them around a lot! The rack itself has held up very well. And after I built the first one (Which took almost an hour), I now can assemble one in less than half an hour. Now for the bad news. The wheels have bent internally, and are literally "falling off!" They have created an added liability, and I am forced to replace them with a more stable caster. This has increased the overall cost, not mention the time and work to remove/replace them. However, it's still less expensive than what an equivalent rack would cost that would have come equipped with such casters. And adjustable shelving, with the plastic adjusters, can have a short life span. Especially if they move or are moved. I would say that this rack is perfect if you're not going to move it. If you plan on moving them around, shop for caster to put on during assembly to save time, and problems, in the future. My recommendation is to STAY CLEAR of caster that have a screw type assembly, such as those that come with the unit. Use one that encases the entire stem of the shelf. I'm using a Krowne Metal 28-151S.

I now have three of these shelving units. I bought two more after about 5 years of only having one. Best roll about shelving and a great price. I use them in the garage to store larger and heavier tools and other junk. I like the casters so I can clean out the leaves and other crap the blows in from outside.
