I had read a good handful of reviews on laptop coolers, but decided to buy this one.
My initial thoughts when it arrived were not positive; the box had English and Chinese (Japanese?) writing all over it, so I thought I had bought something naff,but to be fair - for the price - there is nothing wrong with this tool, whatsoever.
The build quality is not the best, although it is sturdy and the 3 fans are excellent for my 15" HP laptop; they do just the job, cooling my laptop down. Incidentally, I live in Cyprus, so that laptop fan was working very hard to keep the 'insides' cool!
There are no instructions (as described on the box), so I was a bit miffed when I plugged it in (USB connection - no mains power required) and it didn't work; that's because THE ON/OFF SWITCH IS LOCATED CENTRALLY, AT THE FRONT. There are three settings, off, on and one in the middle, but that doesn't seem to do anything.
All-in-all, I am very happy with the purchase and unless you are a person who is more into the asthetics of things, then I am sure you will be happy with this particular product too!
