I am really happy with the service. I have bought a few t-shirts, and they have always arrived on time. What's even better is the wide range of designs available!
But there is something which, in my opinion, is really bad, and at the same time one of the most important things to be considered when buying a customized t-shirt, the printing quality. After a few weeks or months, most of my t-shirts' graphics start to decay. One of them had a text that is no longer readable. This is why I wouldn't recommend this website. If not for this, it would be perfect.
