## Customer Reviews

### ⭐⭐⭐⭐⭐ Great fittings with a touch of modification.
            
*by J***E on June 15, 2019*

Great improvement over stock Ender 5 fitting. Only problem was the filament jamming against the flat bottom of the extruder (brass) fitting. Usual simple diagonal cut didn’t work, had to be like a pencil point to pass through the fitting.  I took a drill bit to make a  very small bevel at the bottom inside of the fitting and now the filament slips in quite easily with just a single snip at the end. The brass is soft enough to just gently hand turn the bit to make the bevel. Just a couple of twists is all it takes, then rinse with alcohol to wash out any debris. Just be sure to use a sharp bit that’s smaller then the threaded part. Just need to slightly bevel the sharp edge, less then 1 mm.  Just remember to just use your hand to twist the bit and not a drill! This worked for me and I will not be responsible for anyone’s bad results trying this method.
  

### ⭐⭐⭐⭐⭐ Awesome Quality-Replace your Creality Couplers.
            
*by G***H on May 22, 2019*

These couplers are really great.  They have thread locker on them already AND a rubber sealing washer in the outside threads.  On the inside of the coupler there are actual metal teeth that grab the Bowden Tube.  This is exactly what you want.  There is no slipping of the tube with these.
  

### ⭐ Flawed Fittings to Extruder ruins the Feeding of Filament through the Bowden Tube
            
*by M***D on July 10, 2019*

The Fittings are off-center and when I tightened the fitting into the extruder unit, my Ender 5 could not load any filament.  This even occurred when I manually loaded the filament through the extruder into the Bowden Tube and into the Nozzle Assembly.  It would not feed any filament even in those conditions.  It would separate my Bowden tube from the fitting and extruder.  I even tried Super Gluing the outsides of the tube down into the fitting.  Completely useless.  If you look at the borders of my fittings, notice how one side has a lot more space than the other side to its threaded sides.  This points to flawed manufacture process for my fittings.  I am returning the items and likely won't by from Ewigkeit ever again because previous reviews have pointed this out to Ewigkeit and they still sent a new customer the flawed fittings.  Looks to be a money grab by the company.  (By the way I wish I would have read the reviews warning me because I skimmed by them when I first viewed the product.)  Live and Learn.
