Same as other reviewers, I was excited about doing stuff through them but their website is possibly the buggiest I have ever encountered. Looks good and modern and enticing but it literally behaves differently everytime you try and use it, empties your cart on its own, does not allow you to delete items you have designed though it says it does- its just full of glitches and yes have tried in multiple operating systems. Im running a high spec'd mac pro with latest operating system- just shocking and how their programmers still have jobs is beyond me
