Shelves were difficult to keep together. Would not stay in insert holes. Very flimsy. And the vertical support beams / corners are weak - they bend VERY EASILY. I decided to move them because they were not that stable.

Good price but needs improvement on the fittings, as they come out easily during assembly. Also very difficult to mount the union of the long and short beams. This union piece needs improvement to make it easier and sturdier.

Horrible product. Putting it together was a nightmare -- so bad that we didn't connect the top part on either of the last two shelving units. Would never recommend this product.

A bit difficult to assemble. It takes 2 people to hold the corners while putting the side panels in place and when placing the top assembly onto the bottom assembly. After assembly it holds together nicely and is very stable.

We tried for an hour to put one unit together and it was so flimsy, we gave up and took it back to the store. There needs to be a better way to connect the top and bottom poles together.

Bought this a few years back to hold storage bins and some tools. This shelving system is a complete joke. It is unsafe as the bottom material that is the shelf warps causing the sides to bow out. We rigged it up with a giant zip tie just to keep the metal frame tight to hold the shelf…btw items on the shelf is under 300 lbs. and each is supposed to hold 600. The entire shelf system we have on it has about 600 lbs total if even that.

Great price, well made with quality material. The only tiny bit minues is that the covers for the top of the shelves were not all in good condition. I guess that's why they seemed to provide a few extra. Otherwise, worked well for the space I needed to organize.

Pros solid plastic shelving vs composite wood- Cons Connection of the top and bottom not very easy to connect top to bottom vertical members. One laps over the other and the shelf bracket holds the two together other shelving units have connection bracket allowing you to put the middle shelf other than in the center of the shelf.

These shelves are a decent value and do exactly what they are supposed to do. However they are also the worst z-rail shelves I've ever owned. The #1 problem is you don't assemble these with a rubber mallet. The pins just fall in the groves with no friction at all. So you can't build it on it's side without it just falling apart. You have to tape all the pieces together. Even standing up if you bump anything before the boards are placed the elements just jump out onto the floor. At 86" inches tall these would seem to be the tallest of the "7 foot tall" shelves and therefore the best value. In reality the bottom end of the column angles are missing 2 holes and so it actually has one hole less storage space than an 84" tall rack. Yes, bottom shelf sits some 4" off the floor, that's where the lost space went. Member's Mark, in their pursuit of cost reduction, made the z-rails out of (even) thinner metal and compensated by making the z-rail taller. A valid engineering trade off except the thicker shelf unit means less storage space between shelves. And finally, one thing I really dislike about these shelves is that the metal edges of the rails stick up above the top of each shelf all the way around. This means you can not slide things like boxes off the front of the shelves, the front of the box has to be lifted up vertically to clear the shelf rail before it can be pulled out. Probably a great feature if these were in the engine room of a boat, not so great in your garage. The photo you see of this rack is not the actual product. It is a previous version of the rack with the narrower z-rails made of thicker metal and providing more storage space. All together I wish I had spent more money on a nicer product.

We found these rack's to be very heavy duty and strong to hold heavy objects. Unfortunately it was somewhat difficult during the assembly to mate the bottom three shelves with the top three. We had to secure them together with self threading screws. Additionally once assembled they tended to tilt forward and we had to secure them to the wall with large hooks.
