Review on 🌈 Fasmov Multicolor Filament: Master the Art of Gradually Changing Materials by Calvin Chavva

This is the worst round spool I have ever used. It is not constantly pushed out by entanglement of the thread. It's just horribly wound on a spool. The only way to get successful prints is to sit next to the printer and correct tangles when I hear the characteristic noise of spool jams. I had three large prints that failed many hours after printing. Last time I spent 8 hours on it and fixed it every 30-60 minutes. I missed a catch because I was feeding the kids and it messed up the print at 8 hours. I have an Ender 3 with a feed lever and I don't have this problem with any other line. Although on a glass pillow holds normally.
