I had a poor experience with them in the UK. The hinge snapped on my ultrabook (I don't remember the exact model as the codes are obscure.) E-mailed support, provided plenty of pictures of the issue. Keep in mind I only owned the thing for 6 months so still in warranty.
Best they would offer is an out of warranty repair.
I know someone with the same model, exact same problem happened to him.
Horrible build quality and support.
