Review on HATCHBOX Purple TPU 3D Printer Filament - High Quality 1Kg Spool With +/- 0.03Mm Dimensional Accuracy And Shore 95A Hardness In 1.75Mm Diameter by Quinton Dawon

This is the worst filament I have ever used. It is the only tpu that has caused clogs, and it has caused many. I have been through probably 15kg+ of other tpu, including other hatchbox colors, but this red specifically, is terrible.The first roll I purchased had extremely out of spec sections in the spool, which wouldnt even allow it through the tighter bowden tube that I like to run for flexibles. I thought that was the reason for the clogs at first, so I purchased another roll which seemed to have better tolerances, but it almost seemed to clog worse. I emailed hatchbox about the first roll, with pictures of me measuring the extremely out of spec portions of the spool, and received no response.I would also like to note that my machine handles tpu extremely well, and I would put my tpu prints up against anyones, so it is definitely not user error or an issue with the machine.In the attached pictures, you can see an example of a failed/clogged print (one of many), as well as an example of a successful print that is printed with hatchbox black, white, and blue tpu, to show how the machine handles other hatchbox colors.
