Amazing!!!
I have been using Microswiss products since bought my first Creality K1, then my K1 Max and now my K2 plus. All of them have been upgraded with the Microswiss hotend and Diamondback nozzles. The combination of the Microswiss hotend and the Diamondback nozzles is the best you can get. I will continue using Microswiss products in all my 3d printers, they just simply are the best ones, no competition.

So Very Worth It!
Spectacular!! It’s the first time I’ve felt like my printer was operating at its true potential instead of fighting against its own hardware.
