For all those that have ordered, check the parts one by one carefully. I made the mistake of not checking thoroughly and now, they refuse to resend me the part. I paid the the kit + the ulticontroller, they only sent me the electronic board for the ulticontroller, but not the main electronic board that should have come with the kit. Now the customer service asked me to buy the board as a replacement for around 200 euro on the website as they blamed me for the fault of not checking. Ultmaker don't guarantee they always ship the right part, and it is their policy not to replace it after a few weeks. This level of customer service, I will never go back to ultimaker. I will just let it mothball and remember the lesson of not trusting a small startup like this one.
