I have a Dell XPS 13 purchased in USA in August 2016. 
 
Very very little use, we actually opened it in December and the only use of it was to browse some websites using Chrome browser. 
 
Battery life is excellent, it seems like it is always on :) Very comfortable keyboard and Backlit and Touch screen infinity edge display is a treat. 
 
Offers welcome, I have listed it on TM as well but prefer to sell directly where possible. 
 
I will provide the receipt for proof of purchase which has serial number etc.

Please PM me to discuss on any offers. We are selling this only because it is not being used and we can probably survive with a chrome book or a NUC.
