Hi vexmatech!

In our experience there is no better flexible filament but flexible filament more suitable for one specific use than other.

Ninjaflex is a great filament as well as FilaFLEX (the first and most flexible filament around the market) but they have specific issues when printing on certain extruders.

We have designed FlexiSMART to be a general purpose flexible filament, not as flexible as others but easier to print and much more affordable since the price of our FlexiSMART is the about the third part of the Ninjaflex (1 kg FlexiSMART 30€ vs 0.5 kg Ninjaflex 50€)

So i can assure you that in a price/quality comparison our FlexiSMART beats NinjaFLEX and others.

Have you even try FlexiSMART? I suggest you to give it a try! If you want to contact us we could send you a free sample.

Regards!
