This is a high quality cart I needed to hold a 65 lb generator and accessories.PROS:1. strong enough to hold heavy weight.2. wheels are solid & strong; all have a lever to lock each individually. rolls smooth.3. cord holes in metal shelves are a nice touch with included rubber donuts to cover sharp edge.4. two non-slip rubber mats that you could you cut holes in if you wanted to match the cord holes.5. lockable large cabinet that will keep out toddlers, most kids & your dog. Not for securing valuables.6. detachable power strip with 3 ac plugs and 2 usb. very nice! also cord can be wrapped around for storage. I suggest test your strip right out of box. Mine was perfect. This was a key feature for me.7. several adjustable heights, key board pullout can be optional.8. all pre-drilled holes in the steel matched up perfect when assembling.CONS with solutions:1. NO INSTRUCTIONS were included!!! Seriously? And customer support seems invisible. I'm pretty handy, but it took a couple hours to figure it all out by looking at the pics and other vendors pics selling the same unit. I laid everything out in detail and just started with the easy parts 1st (wheels). a. The vertical supports go outside the shelves and cabinet. b. I added a washer under all the bolt heads (only cause it spreads pressure and keeps the finish from a lot of scratching). Washers are not included, I just happen to have a bunch of them. c. I had to play with the cabinet lock mechanism experimenting with various positions with the catch until I found the magic combo and it locked smooth and tight. 2 keys included. (I will be storing them in a magnetic car key holder under the shelf). d. The keyboard slide is trickiest. Measure carefully. The pressed wood shelf DOES NOT have pre-drilled holes, but that's likely cause you have 9 holes in each slide to choose from (using 3 screws). 2. It took forever to figure how to release the slide part you have to screw onto the shelf. There is a tiny rubberized fl
