I bought it to replace another flimsy one that was dragging on a heavy desktop server. The three wheels went in easily, the fourth just wouldn't go in no matter what, I pressed it with my foot, there was a crack sound and it finally got fixed in place, for how long I don't know. It is shorter in length than I expected but it looks sturdy, for now it works.

Good and economical. I have installed the computer tower. The downside for this case is that the size is borderline.

OK, what you see is what you get. Good - relatively - construction, it holds the tower comfortably and helps (if you have a floor) to easily move it, clean, etc.

Perfect. What it said, that's it!!!

Very immobile. Once I was trying to push it further (with the wheels unlocked on a wooden floor) and I just dropped my computer down. Without wheels, my computer tends to slide more easily on the floor. Also, it sits somewhat crooked on the base. Overall, it doesn't perform very well, the only thing for which you buy it (besides the fact that it holds the computer high)

Cheap plastic that lasted for a short while. The wheels get stuck in plastic cases, so you can understand that you have to handle it very carefully. It's not meant for heavy use, if you don't plan on moving it at all, it works.

The wheels lock easily. Very convenient and adjustable in width to fit any size computer.

Plastic construction, however, it does the job just fine and even for a relatively large tower that I have.

Good, very economical. If you need to move it often, it may not be convenient for tall objects. Also, the base is only 31 centimeters long, so check if the object protrudes. Personally, because the "feet" of the object I put (a small dehumidifier) are on the part that protrudes from the base, in combination with the "shiny" plastic, I had to put double-sided tape to prevent it from slipping off the base. It does what it promises adequately and nothing more. Personally, it's okay for small moves, but for moving to another room, I end up carrying both the dehumidifier and the base!
