First unit half worked, but second has been better

The VGA video part worked fine, but on the USB connection to my laptop, the mouse & keyboard kept disconnecting & reconnecting to the computer and each time they would freeze up until reconnected. Very frustrating. I am returning and trying something different. August 2018 update - Seller sent me a new unit at no charge and it seems to be working much better, so I am increasing my rating from two stars to four.
