Bad TPU do not buy
After printing multiple rolls of their black and white low shore hardness TPU, I cannot even recommend TPU from this brand to my worst enemy. Very inconsistent and lumpy diameter, lots of wiggles aswell. Causes frequent jams and will make you throw away so many prints you wish you bought something twice the price to save you the headache. It can (sometimes) print, and when it does there's no issues with the material itself, but the quality control is absolutely garbage and you pay triple on the backend with the savings you made upfront.
