No problems at all!
Bought a couple of t-shirts spontaneously, then decided to read the reviews. I was pretty worried, but everything turned out great and I really like the t-shirts. I'm a UK small but a Large in their sizes - can't really blame the company for that, and they have a pretty clear size guide that helped me pick the right size. They arrived on time as well - just under 2 weeks which is fair enough for a product from China!
