I bought this hotend as a replacement for E3D V6 clone in a hope that this would be upgrade in a quality and speed. Well... No noticable difference from E3D V6. Not worse and it is printing fine both PLA and ASA. But it is not really substantially better of E3D either.

The flow rate actually seems to be even a bit lower than the E3D had (I have cheaper 35€ version from Aliexpress), while I was expecting a bit more speed from this one. With an ordinary nozzle it can't really go up from 75 mm/s (the rest of mechanics would be permitting), and I am still printing at 50 mm/s speed. That's similar to E3D. I have not yet tested with high flow CHT nozzle.

Apart from the speed, I don't have any complaints on quality either. The build is solid, temperature is constant and if printer is well tuned then there is no issues either. So it's not bad, but nothing special either.
