Review on ESUN Printer Filament Dimensional Accuracy by Ben Diesel

I ordered this in hopes of printing some things with bright ever changing colors. Imagine my surprise when the first things I printed were mostly gold with no visible color changes. Hm. Now I've printed a lot of things and now I see the color change. Sometimes the gold is greener, sometimes yellow, sometimes orange. But we don't see bright reds, yellows, greens, or purples. This is apparently not the same rainbow. It doesn't matter that "rainbow" means a specific color sequence. The filament is good, as good as other eSun products I've purchased. There are no complaints about this. And I'm not going to send him back to complain to them about it. But you should be warned that this thread is NOT for you if you are looking for rainbow colors. So consider yourself forewarned.
