I purchased this coolant because it has a sleek and nice design, not forgetting its extra 4 USB ports located behind the coolant. However, it seems that the USB ports are not as good as the usual USB port on my laptop. I tried plugging my external hard disk and it failed to detect it. In addition, I tried charging my portable battery but the connection was really unstable as my battery light kept flickering, hence I decided to charge it using my laptop USB port.
Nice design and it works well as a rather good laptop coolant, but quite disappointed with the USB ports though.
