Query: Great product

I bought this for multiple reasons. One is that I have more devices than usb ports on my laptop. Two, one of the usb ports on my laptop died, and Dell refused to do anything about it. I have had this product for a few months now, and I have not had any problems with it at all. I was a little hesitant at first to get it, because of some other reviews. They said that it dies after a couple of weeks or months, and gets hot. I have not had either of these problems. It stays cool, and is fast. I do not see any reason why someone shouldn't buy this product.
