I ordered a XPS 13 in 2014 over the phone since there was a problem with checking out at the website at the time. I spent 15 hours (started logging hours after the 2nd) total fixing their mistake when I realized they didn't order me the developer edition. Those hours were also spent fixing the screw up of them sending it to the wrong address.

I did end up getting the laptop. It was pretty nice except I could hear an electrical hiss coming from the bottom of the laptop when the room was quiet.

I had a friend who had one and confirmed the sound was coming from his as well.

I sent the laptop back and spent another 2 hours with their "support" for that.

I'll never buy from Dell again.
