Review on 1Kg Spool of Monoprice Crystal Clear ABS 3D Printer Filament by Brandon Grzankowski

This filament is cheap and inexpensive to manufacture. I printed a few rolls - both were very tangled - and kept jamming due to roll tangles so bad they wouldn't feed. After you used a third of the roll, the tangles were less, but then crumbly spots started. Each spool had spots so dry and crumbly that the filament broke trying to feed it. You can just crumble it a foot or two, it breaks into pieces with a light squeeze, it doesn't look like ordinary filament - and then the filament returns to its normal flexibility. Someone told me it was supposedly mislabeled. PLA not ABS - a plastics expert told me to burn a little and if it smoked it was probably ABS and if it smelled sweet it was most likely PLA and it smoked and smelled sweet. ABS and I got some great deductions. I printed the T-Rex head and it didn't break during printing and looked amazing - then I couldn't print a mounting stick without warping. I printed a twisted star vase using a piece of vase and it came out waterproof. But I have had prints that have failed due to curling and others due to tangling. If I had to guess, it would be a mix of plastics, possibly poorly sorted recycled plastic. Don't do it unless you're worried some printouts won't work.
