I wasn't expecting much when I bought this. This was my fourth attempt to be comfortable while at work. I run my business from home and am a total workaholic, so I guess I caused this problem. I've tried lap tables, TV stands, and a cheap similar version of these. I have a heavy laptop so they either tip over, can't hold their position or overheat my computer. This is everything I dreamed would be different. It's heavy and well designed. It has all the possible positions I need, high, low, angled. Each position setting is locked at this point until you unlock it. It's wide enough without taking up the entire bed. Holes on the bottom provide ventilation for the laptop to keep it from overheating. It also comes with an attachable mouse stand but I can't figure out how to attach it and I don't need it so I threw it away. I could buy 3 of these with all the money I wasted on useless competitors. It's worth every penny!
