This is a great addition to rolling workstation. Overall, it's sturdy and there's nothing really bad to say. It works okay with a regular mouse but definitely is better with a trackball mouse. Being nit picky, I'm not sure why the groove at the top isn't bigger if you really want to hold a phone with a case and the little mouse storage would probably be more useful if it faced the other way because I honestly forget it's there. Overall, well worth the purchase.

Love the mouse tray! It was very easy to install, following the instructions that accompanied the tray.

The adjustable mouse tray is a great addition to my laptop stand.

The laptop stand was fantastic and easy to assemble. It has afforded me flexible office space to flex up employees with a mobile work station

I love the Levo laptop rolling workstation and the mouse tray is the perfect addition. It is adjustable and I tilted it to match the angle of the laptop. The surface is very smooth so I added a neoprene mouse pad and put 2 rubber bands (top & bottom) to keep the pad in place and the rubber bands let me keep memos there too. I highly recommend the mouse tray/shelf if you're mouse-user like me.
