Update: I've lowered my rating to zero stars on this filament. While it prints nicely, quality control sucks, and it gets as wide as 2.3mm in places, causing jams. 3 different rolls each had at least 4 places where this occurred. 

This TPU is very similar to the slightly more expensive Zyltech. With a durometer rating of approximately 98A, it prints very nicely (albeit at slower speeds). 

Print settings:
Nozzle at 230C
Bed at 70C first layer, 80C second layer, on clean glass plate. Do not print on buildtak or other flexible plate unless you first spray hairspray on the plate. 
Print speed 20-30mm/s. If you have an extruder made for flexible filament, you can print as high as 80mm/s.
