I'll give ikier a 5 star because they are an overseas company. You have to be patient and be ready to send pictures and videos. I haven't had a lot of problems with my k1 ultra, but things do where our. I email them with my problem and I have an email by morning because of the time difference. It's usually a week or a little more for my parts to arrive. I've learned to fix a couple things on my own, they send video of the process. My z axis motor is my next challenge. Thanks for replacing it at no charge Ikier!
