Solved my clogging issues

Switched from standard PTFE and the difference is night and day. Filament feeds much smoother.

Decent but pricey

It works as advertised but I'm not sure it's worth the extra cost over standard tubing for basic PLA.

Great for abrasive filaments

The stainless steel lining holds up well against carbon fiber filled PLA.

Good quality tube

Works well with my Ender 3. Slightly stiffer than expected but holds shape nicely.
