Lapworks is a big name in the field of ergonomic laptop desks and desk stands. I have been a long-time user of the Futura laptop stand from Lapworks. It is simple and is great for using the laptop on my lap. It helps with cooling and it saves the family jewels.
The Attache is a beefier laptop desk than the Futura. It is made in a more solid aluminum with a plastic bottom. It has 2 cooling fans embedded into it and it does seem to help with cooling of my DV6000 (a laptop that gets super hot underneath). The stand also has a 4-port USB hub built right into it. This is super convenient.
The power fans both draw their power right from the USB port on my laptop, using the provided USB cable. This would obviously be enough to run simple USB devices over the hub (like a mouse or keyboard). Since the hub is not independently powered by an AC adapter, you would not be able to run devices which requires more power yield.
If you use your laptop as a desktop replacement, the Attache laptop stand is a pretty good way to go. I like it much better than the Aluminum Desktop stand I reviewed for them a few months ago. They charged the same amount of money for that stand, and I thought it was overpriced. The Attache is offered at the same price, yet I see much more value here with the included USB hub and the cooling fans. Besides, I can actually figure out the Attache! The other aluminum stand was confusing at first. Looked like a big hunk of metal hinges!
All in all, I give the Attache Laptop stand high marks.
