Summary: I purchased dell xps14z about a year ago. The product looks quite good. The performance of the dell xps14z is good except for wireless connection. sometimes it is very hard to connect to wireless network unless otherwise you are 1 meter away from the router (then it works okay). I have contacted dell to solve this problem they gave it a few tries but never solve the problem. As I said, the computer is quite fast and the performance of the machine is good.
