Slapped it together and it works great! Like the adjustments for the laptop shelf up and down, and the tilt is really handy and what sets this apart from others. The wheels would probably work great on a hard surface, kinda useless on carpet, but what can ya do? A handy device and I'd say worth the extra bucks for something you can use. I'd heard some say it's to low to go on their beds. Too bad, so sad. I don't use the laptop in the bedroom because I'm not paralyzed or bedridden. If you are either of those, you might need something heaftier. Hope the review helps somebody. Happy 4th of July America!
