The first thing that struck about this product was its complete light-weightness. It appears to be made out of nothing but light, poor quality plastic and lacks and kind of strong durability. This was compounded by a friend's recent purchase of a similar product, which was of a considerably higher quality in this regard. In terms of its use, it more or less fulfils its duties as a USB hub. However, I have found that it simply will not work with a USB midi keyboard that I have. This is not a huge deal as I am able to connect the keyboard through my other USB port, but it is at the same time a bit of a disappointment. Perhaps it is a case of getting what you pay for, but I definitely pay more for better quality than this in the future.
