Bought a 3d printer for a Xmas present. Informed them within 2 weeks of a fault, they insisted on us speaking with an engineer. We sent images, emails and advised that their fix of a firmware update hadn't worked. It took 2 weeks and a very heated phone call to customer service to get an email back to which we responded promptly. Still waiting for a response 3 weeks later. We are now well out of the returns window and they are refusing to replace stating they have to test to find the [intermittent] fault and if they don't find it, we won't get a replacement. Spend a bit more and buy from a reputable seller that you can actually get hold of.
