I could not find reviews on this keyboard tray anywhere, and I was hesitant to purchase it because of that. So glad I did! It raises up higher than any other tray I saw and it's sturdy! I can raise it all the way up and rest my elbows on it or write on it while in a meeting. This keyboard tray is very heavy, but easy to install with the template provided. Make sure you measure well, because this tray is BIG.
My only complaint is that I wish the tray swiveled left to right. I can't knock a star off for that though because I knew it didn't before I purchased it.
All in all I'm very pleased with my purchase and would recommend both the product and the shop.
