I bought one of these recently from Amazon as a stand for my netbook. The majority of "ergonomic" stands are simply too big and bulky to carry around easily with a small netbook, which was what first attracted me to this product. I've seen these for sale elsewhere online (often described as a "Cricket laptop stand") retailing for between £30 and £60! Definitely a bargain here on Amazon! The stand raises the screen of your device up to a more comfortable (and healthy) viewing angle, and also helps keep your device nice and cool, as it maintains an airflow all around it. I use it with a Targus mini external folding keyboard and one of Trust's micro mice. Thus, even in my small netbook case I can carry all my kit (including my power lead and a small external optical drive) so I'm fully kitted out and can use my netbook in comfort when I'm on the road.
When the small package arrived, it was (pleasantly) surprisingly heavy for its size - I was expecting something not quite so substantial for the price. Folded its dimensions are 20.3(l) x 5.1(w) x 2.5(d)cm, and it weighs in at 177g. The maximum netbook/laptop/tablet PC weight it can hold is 5.4kg, which with the weight of portable computing devices these days, should be fine for all but the largest of modern laptops.
It comes in its own drawstring black pouch, which is a nice touch, and it's small enough to just pop into your pocket, laptop bag, or any other bag you care to pop it into. This is a product that feels well made and not at all flimsy. Depending on the size of the object you're using it as a stand for, you can either simply use it with its 'legs' unfolded, or adjust the height of the front two legs. I use it with my 10.2" netbook, and it's fine without the legs extended, but for a larger laptop possibly you'd need to use it with the legs extended to make it more stable. As the product description says, you can use it with a tablet PC or a netbook/laptop, and at a push I guess you could use it as a book/document stand as well.
Unfolding it from its closed position is simply a matter of pressing the large silver coloured button where it hinges to set the angle of the 'back' leg. The height adjustment is from 11 degrees to 60 degrees (in six increments, at each of which you feel a nice solid 'click'). The two front legs simply pull out sidewards to your desired width, and with the legs set up, you then pull out the small rests on each of the two front legs to rest the leading edge of your laptop/netbook/tablet PC on. Although the rests are plastic, they feel pretty substantial, and are 'serrated' to prevent slippage.
All in all, a great piece of kit which you won't regret investing in.
