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 Jeff Shapiro

I was amazed that the every first print came up well using my default PLA settings. And it is on 3D-printer with bowden extruder (FlSun Kossel Delta). Sure you can't print with this as fast as with PLA if you printer using bowden tube. My settings were: 10.mm/s outer perimeter and 40 mm/s infill. It is also recommended to set up your extrusion value 5.10% above your normal setting. The part you see on my pictures were done using my regular PLA settings (210C nozzle, 70C bed - kapton tape on aluminum plate, sticks well!) - and it is clearly slightly underextruded due to the nature of how TPU filament works with extruder gears.
