Great cart! Very sturdy and solid! My only issue is that I needed tools to assemble it. My "modification" was to purchase wing-nuts from my local hardware store. I can now easily, and without tools, adjust the height.

I bought this to use at work. Wheel pivots took a little while to loosen, but now work well. A push handle would be nice. Built sturdy.

Overall, a very nice and sturdy A/V cart. I got it to use for oscilloscopes, frequency counters, signal generators, and similar test gear, and it does an excellent job for that. It was boxed well for shipping, though UPS did their best to try and destroy it, but I was able to bend everything back straight. The welds are done quite nicely and easily withstood the abuse of shipping. The door works quite smoothly and is aligned perfectly, and the full piano hinge really helps with that. The wheels roll very smoothly with no binding. And the steel is a decent gauge thickness and not overly flimsy. I picked a steel cart to minimize static electricity when using it around electronics, compared to the all plastic carts.

Now for a few negatives. As other reviewers mentioned, it's good to put two screws on each upright for the top section rather than just one, but it only comes with four screws. My guess as to why is because the pairs of screw holes don't fully and completely line up to put two screws in. They probably originally designed it for two for each upright, but dropped it down to one when they realized their design was off (or that's my hunch as to why). That means you have to drill out the holes slightly to install additional screws. If you are wondering what size screws it comes with, they are 5/16"-18 x 3/4" button cap head screws with nylon lock nuts -- you'll need four of each if you wish to add additional screws.

Another negative is that the screws for holding the power strip in place only have wing nuts, but no lock washer to keep them from loosing over time. You'll probably want some #8 lock washers for those -- you'll need at least two. I used external tooth lock washers rather than a split ring version, as I thought it would work better.

Another negative, as mentioned by others, is that the rubber anti-slip mat doesn't have the hole cut already for the power cable feed-through -- a minor nuisance as it isn't very difficult to cut, but does require extra effort to mark it and cut it. It would have been nice to be done already. Also, it only came with one rubber mat and it would be nice to have two -- one for each shelf.

And the last negative is concerning the power strip. It came with a plastic retainer piece for holding the power cord in place for when you wind it up for storage. That retainer is only on one side and it really needs to go toward the top so that it works with gravity when winding the power cord. However, I would have liked to rotate the power strip around so that the power cord comes out the other end, so as to put it on the back side and work better when using the cart. But rotating it puts the retainer on the wrong side. So, the strip needs to have a retainer on both sides and/or it needs to be reversible or have the cable exit on the bottom. Also, three outlets isn't really enough and they are turned wrong if you have any wall-warts to plug in. That means, you will have to get additional power strips for most usage cases for the cart. They should have provided more outlets and turned them to be used more conveniently.

The assembly is fairly quick and simple, but you do need a few tools. First, you need a giant rubber mallet to beat things back straight and to drive the wheels into place, and you'll need a small block of a hard wood to use for driving the wheels in so you can apply the force straight down into the shaft of the wheels and not be hitting it at an angle with all the force on the axle.

If adding additional screws, you'll need a drill to drill out the holes slightly, along with a 5/16" drill bit and a shop vac to vacuum the shavings out of the storage compartment and off the floor.

For tightening the screws, you'll need a 1/2" socket on a standard 3/8" ratchet with a short extension. The reviewers complaining that their wrench won't fit probably weren't using an extension, or perhaps they were trying to use a combination wrench instead of a socket wrench. But you will need a socket wrench and you will need the extension. You may also need your own hex key wrench. It comes with one, but the one I received seemed to be sized weird. It would fit the screws that came with the unit, but not the extra screws I got for making things stronger. However, when I used my own hex key wrench, it (strangely) fit both sets of screws perfectly.

And you'll need a phillips screwdriver for tightening the screws for the power strip (don't forget to add the lock washers or some thread locker). And you'll need a marker pen and a hobby or utility knife to cut out the circular opening on the rubber mat for the power cable hole.

Overall, though, despite a few negatives, it's a pretty nice cart and does everything I wanted it to do. It's sturdy and rolls smoothly.

Not a lot to say -- it's a basic cart, at a basic price. We use ours as a mobile workstation for a computer that can be used standing up or with a bar-height chair. We made a small top for it out of plywood with a 6 inch overhang on the front to provide kneespace for when it's being used with a chair.

The cart is pretty sturdy. It's kind of a pain putting the top portion on - it' useful to have a nut driver handy for that task! Also, the rubber mat for the top shelf barely grips, so items on that shelf slide off fairly easily. Other than that, it's a good cart for the price.
