    You have to know what to expect
  

*by L***G on Reviewed in the United States on February 16, 2021*

This is NOT like regular flex TPU. It is MUCH more flexible. You HAVE to make sure your printer is set up to print VERY flexible filament. I have two bowden tube printers and get great results with a simple modification to the extruder feed path. A few mm long piece of bowden tube cut with a 'V' shape at one end is all it takes. Just have to get rid of the small gap between the extruder drive and the bowden tube going to the printer. I just let the short tube float above the drive wheel.I do have to bump up the feed rate to 1.2 and print SLOW... maybe 20mm/s.Nice smooth results on naked glass as it sticks very well to a warm bed. I am using between 50 to 65c bed temp.My only complaints are;very expensive for a 0.5kg roll.for some reason they use a spool that is BIGGER than a standard 1kg.  (mostly empty and too big to fit into a 1 gallon zip lock bag. I noticed the few rolls I got never come in a vacuum bag and print perfectly so I assume moisture is not a factor with this.Once you get it dialed in though... prints nice.Understand this is NOT like regular TPU.It is a specialized filament for very specific uses.

    I printed this on my prusa i3 mk3s. This was my first filament that wasn’t pla or petg, i found a printing profile online and was able to use it to get pretty good, and flexible results. There are minor imperfections, but those can be fixed with some tweaking. This was the first print with this filament and im pretty happy!

    Good TPU but really needed dried
  

*by K***E on Reviewed in the United States on June 16, 2021*

VERY VERY soft. Seems like good quality. Prints easily with my micro swiss direct drive. Printed on unheated garolite bed perfectly. Only complaint is it came unsealed and DEFINITELY needs dried. Lots of popping/fizzing and tiny puffs of steam from it as its printing. Might update again depending on quality when dried.
