My time at YOYI was a letdown for me as a do-it-yourselfer. Even though they promoted themselves as "the one-stop shop for all your 3D printing filament needs," they actually had a smaller variety and higher prices than competing sites. Several unsuccessful prints could be attributed to the filament's poor quality. When I needed help, I was met with silence from customer support. If you're searching for affordable and dependable 3D printing filament, YOYI is not the brand for you.
