Have the reader bought for my Cadillac CTS and it works immediately. Read out fault, delete, store separately. Real-time data capture works great. Tried also to a Mercedes C-Class W203 device. Fuktioniert also immediately. To the customer, I can not say much, because the device works perfectly. Fits comfortably in your hand. The information is easy to read on screen. There is a driver CD and a USB cable. The drivers or updates can also be downloaded from an external source in German.
