I have had at least a dozen of this and the corresponding aluminum-colored model - some for over two years. All have worked (and are still working)flawlessly. The only weakness is the connection of the power cord to the external power supply. If you are careful with that there is no problem.(I am a retired computer science professor and have dealt with many of these products)
