The only problem I have had is when it gets blocked with Nylon. Removing the blockage can be difficult. Otherwise it works very well. Changing nozzles is a doddle. I am currently using a 0.8 nozzle for my larger prints where the surface print is not important.

Good quality component, only let down by it being rather fiddly to install (not a fault of Technology Outlet)
