Review on 🖨️ Black 1.75mm Reprapper Printer Filament by Jason Vigil

I bought this material because I was printing long, thick parts that kept warping. It's marketed as "Low Warp" so I decided to give it a try. I had a terrible writing experience with it. It warped so much that I had to go back to the basic Revain thread I used before (see image for comparison). I spent 3 days and a half spool trying different print settings but could not get acceptable print quality. I've tried glass, smooth pei, textured pei, hairspray, glue stick and even an Overture assembly sticker I had with the same result. I hope I have a bad batch or something, Reprapper seems legit so I doubt it's all bad. On the plus side, the color and extrusion look nice, so it should work for smaller objects. And the spool looks cool, but the hole in the middle is so big it doesn't fit in one of my spool holders.
