Mayline Small Home Office Portrait PC Desk Cart - Compact & Stylish Computer Workstation for Small Spaces | Perfect for Home Office, Study Room, or Dormitory

This cart is easy to assemble, however, the instructions, which are diagrams only could use an important note. I read reviews of this item on other sites and noted a common complaint about the keyboard tray. I believe I've discovered the problem and the solution is pretty easy. I was tempted to give only three stars but that felt unfair as the cart really is quite nice.The problem with the keyboard tray stems from the assembly of panel H with is the first item to connect the two sides. You see it in the picture just below the keyboard tray. There are two bolts on each side. The sides themselves are metal tubing, plenty strong for their job, but when one tightens the bolts the light steel of the square tubing is very easy to compress because there's no sensation of having gotten the bolts tight.The trick here is to just snug them up and not tighten them beyond finger tight. The assembly might seem a bit loose but it's only a temporary problem until the top and bottom shelves are installed, and actually make installation of those easier. The keyboard tray is supported by the two arms that extend from the sides and hold the sliders. These are cheap sliders and one of my reasons for taking off one star. Overtightening panel H causes the arms to skew outward from each other. The angle is slight and not noticeable until one inserts the keyboard tray into the sliders with is the very last step. That angle causes the keyboard tray to be difficult.This morning I loosened panel H on both sides, took the keyboard tray off and gave the sliders a good look. There is a short bearing race on both sides that slides back and forth. One side moved freely while the other had been jammed from my attempt to push the keyboard tray all the way back. Moving the jammed race forward and carefully and gently making sure that both sides were engaged cured the problem. I still can't push the tray all the way back as I would like, but it's really not a big deal in my situation. I'm guessing the keyboard tray is 2 1/2 to possibly 3" further out than it would be if fully closed. I can live with that.This entire problem could be avoided with an installation note about finger tightening only for panel H, and using a better set of sliders. I would pay another $20 if I knew that was the reason for the price increase. If it was a big deal, I could purchase a better set of sliders locally and replace the ones that came with the unit. They bolt to the arms. That might mean cutting the keyboard tray to fit afterwards. Since I'm a woodworker and have a table saw, not a big deal for me. That's a very big deal for others.So, if you're careful in the installation, and can live with the tray not going back 100% this is a very good and sturdy cart that looks very nice and is easy to move around. The casters seem to be of good quality and actually bolt on vs. the snap in kind I see so often. I elected not to put the side (CPU) cart on because it didn't fit the space I needed to put this in. I suspected I might not do that when I bought it so no deduction there.So, manufacturer, if you're paying attention, you have a nice product that with some easy changes could be made much better.
