Kobra 3 V2
I use my Kobra 3 V2 for my business, so any downtime is a huge problem for me. After a recent firmware update, I got a critical sensor error (Error 10129) due to a broken wire. I contacted support and was assisted by Nelson. I was worried it would take weeks of back-and-forth, but Nelson was incredibly fast and efficient. He quickly analyzed my case and immediately approved a warranty replacement for the entire heated bed. The instructions to provide my shipping details were very clear. I am still waiting for the part to arrive in Brazil, but the customer service experience so far has been perfect. 5 stars for the agility and respect for the customer's time!
