Excellent !
I have bought several smartphone (6 in all) and tablets (3 in all) through 2-3 years, for me and some friends and everytime go smooth. I only have one time a problem withs customs. The smartphone remain blocked at italian customs and the company send a new one, that arrive quickly. After more than a month arrive the first smartphone and the company arrange for picking up with no cost for me. After a while (a couple of months more) arrive me invoice for custom clearance. I paid this and grossoshop refund me in 2 days. I think the best european ecommerce for brand like xiaomi or other chinese brands.
