Apparently, first print quality was not enough for the supplier (it was good for me! :) ) so he sent it along with a second one, better polished. That was great, thank you!
Ordered an button plate for my sim racing wheel with no special requirements - I was asked if I have any requirements before the print was started; when it was finished I got a picture if I would agree to ship it.
While having problems with DHL I was offered a second print if I need the printed part in a hurry.
5 star rating - for communication and customer service I would like to add a sixth one :-)
