New (portable) computers or small computers are often delivered only without CD / DVD drive. When installed, when playing media or for data storage then results usually a problem. The device is small and handy and fits into your laptop bag or in the desk drawer. It does not require external power supply and draws power through the USB cable. With Windows 7 and 8 there are no problems with the recognition. The performance values are good (USB 2.0). For operation you need some space, especially when opening. Some CD / DVD there is noise generation. Price-performance voting buy!
