This laptop table has the right ideas, but it's a pain in the neck to adjust. You have to adjust stiff "legs" one at a time, remember the degree you placed on one side and then do it again for the opposite leg. It was too much work! After spending 10 minutes adjusting the stiff legs on the right side, you then have to do it for the left side. Then it was too unstable, you had to try different heights (which is extremely annoying when you have to do it again for the other side) if you own a 17" laptop like I do.
The fan is a good idea but that's not what I bought it for, I wanted to be able to use my laptop in bed. It doesn't do a good job with a 17" because it's not very sturdy. In less than a week, the spring broke loose from one of the knobs.
I just bought a simple board one from Costco instead and it was a whole lot cheaper and more versatile since I can use it as a laptop and a book-stand, plus, it cost me a lot less than $100 and Costco has a flexible return policy if I didn't like the product.
Cons:
Too flimsy
Too stiff
Does not work well with a 17" laptop
Is difficult to adjust
Too much adjusting and leveling to get it stable
