So my printer came from the pioneer program my printer is the k2 pro. I have had some issues most of it was my fault like using a brand for the first time and not dialing it in. There were some software issues but was resolved with a restart. There has been times where I had to take apart the nozzle due to a chunk of filament breaking off in the extruder and that was super easy compared to some other brands. Honestly every one that has an issue complains about support but once you learn the channels of communication I usually get the part shipped by the end of the week. For me the experience has been positive but of course for me I do tech support so if something happens I start to troubleshoot.
