If you own a 3D printer with a heated bed and a high(er) temp extruder (260-285 deg), these materials produce a superior quality part. Especially the Z-Ultrat low shrinkage ABS.
I have tried dozens of materials over the years (I am a product design engineer) and I have basically settled on using Z-Ultrat exclusively. It's usually frightfully expensive $70-90.
At $22.50 basically theft. The same you'd pay for poor tolerance Chinese filament you wouldn't make a door stop with.

I print with cheap chineese ABS everyday, half of my Voron 2.4 is made of them too lol
But… If you say it's really good I'll give it a go and see the difference, cheers!
