Works well, decent price, average length. If you’re replacing your hot end or extruder, you may as well pick up a new Bowden tube. If you’re using this on parts with a compression fitting like the dual gear extruder or the cr6 hot end, I recommend running a piece of filament through it while you tighten down the nut to squish the brass olive. It will help keep you from crushing the tube so much that it blocks filament.
