AQNIEGEP3 Shelf Utility Cart Heavy Duty Rolling Cart with Brake Wheels Storage Service Cart w/Deep Shelves for Warehouse Workshop Cleaning Office Restaurant Commercial Moving 600lbs Capacity Black

So far so good. I expected to be not great given the price but this cart works really well!

This cart looked like it would be perfect for my solution, and I wanted a cart that is bolted together, not just shelves stacked on each other like many others on Amazon (how are you supposed to lift up the handle to get over a hump if the cart falls apart when you pull up on the handle??). The top shelf gets three screws into each of the vertical posts, and the wheels bolt / nut directly through the bottom shelf and through the vertical posts. I also needed three tiers for my application so many others would not work.The quality of material and build are pretty good on this unit, but there is one area in the 'gusseting' under the top shelf that looks like a real crappy after-thought repair. I was pretty discouraged, but when I came here to vent about it, I see that the unit used in the description photos looks exactly the same? Seems like a problem with the mold or whatever process is used to make the top shelf (there's no way they intentionally mold it this way?). It doesn't appear to be cracked, but it looks pretty bad. For my purposes this strange 'defect' doesn't appear to reduce the load carrying capacity enough for me to worry. Attached pics for reference.One other issue is that the description photos misrepresent the height between the shelves. The pic clearly states 11.5" gap between shelves, but its not even close. I needed at least 10.5" so that I could slide a large battery pack (Bluetti B300 fyi) onto the second shelf, but there's no way for that to happen when the gap between the lip of the second shelf and the bottom edge of the top shelf is only ~ 8-1/4". The space between the floor of the second shelf and the bottom of the top shelf is just barely 10-1/2", so I don't know where the 11-1/2" spacing comes from.This thing is too big and clunky to repackage and send back, so I am planning to just modify the 'wall' of the second shelf and cut it out so that I can slide my battery pack onto the second shelf. I don't thing the load bearing capacity will be reduced enough to matter. FWIW, I thought about modifying the cart columns so that I could relocate the second (middle) shelf one 'slot' lower (creating a larger gap between top and second shelf and a smaller gap between the second shelf and bottom shelf). FYI there is no way to do this easily, because only the middle 'slot' for the second shelf doesn't contain little knobs for reinforcement, which keeps the second shelf from fitting anywhere else without cart modification.The wheels are nice and fairly large for rolling over doorway thresholds and whatnot. Two are swivel and two are static, so pay attention when installing them. I placed the swivel wheels at the handle end of the cart, as that seems to be the easiest side to maneuver from. I noticed a slight bit of 'teeter-totter' when the cart was empty, showing that its not built completely level, but once some significant weight goes on the cart it flexes enough to sit flat on all four wheels.In summary, I feel like this was worth the chance I took (no review history on it at all). Its a sturdy cart and everything goes together pretty easily. The material is solid and plenty thick, inspiring confidence that it will hold a lot of weight. The manufacturer should fix the weird gusset problem with the mold on the top shelf and it would be pretty darn perfect. The description photo and measurements shown need to be adjusted as well. If you need a solid cart that wont rust, wont get all scratched up, and wont fall apart if you have to lift up on the handle to get over a bump, then this ones a winner. 4 stars only because of the molding process problem on top shelf.

These are great, heavy duty, but 550 lbs is clearly marked on top shelf, not 850 lbs
