I printed a base for the spool with bearings so that I don't have to remove the tube; otherwise the filament doesn't pass through well.
On the Bambulab A1 there are no problems with printing

all 3 boxes were damaged, as in dented, I don't know, looked pretty abused. but that's a box. not too important, but it shows some people in the chain clearly don't care too much. However all 3 spools were also wound up too tight causing a litany of problems.

Simply a pain to print with. Compared to Sunlu and eSUN TPU, this is unacceptable. I have thrown away more than half a kilo trying to print something complete but it just doesn't... Of course, the necessary calibrations have been made.

For a 95, I expected it to be harder; this is too elastic to the point that it gets thrown off the feed. Other than that, it's good and very strong.

I expected it to print much more difficult and much worse. Especially considering its price.

Yet it surprised me, it printed perfectly on my Bambu A1 with Generic TPU settings, at 220°, and produced one of my best benchys. The only "extra step" needed compared to typical PLA is that I fed it directly into the printer's head, meaning I removed the PTFE tube that usually guides the filament. Overall, very easy. It only struggles a bit on overhangs, but that's due to the type of plastic; there's nothing we can do about that. Oh, and literally zero stringing.

When I bought it, it was €10 cheaper than any other TPU brand. I will probably buy more colors.

I haven't tried any other TPU, but the results are very satisfactory. All prints are very durable and after almost any deformation, they return completely to their original shape.

One problem I encountered is that the extruder of my printer (Bambulab A1) couldn't always pull the material, creating gaps during printing. As another user mentioned in their review, this was solved by removing the PTFE tube and pulling the filament directly from the roll to the entrance of the extruder, without using any tube or "guide" for the filament, because they create a lot of friction with this material and due to its elasticity, the extruder can't pull it either.

Wonderful results with Bed 45 degrees and nozzle 220-230 after temp tower. First time working with tpu, made the base go straight to the head. Printing for 3 hours without any issues.

Difficult material, the equivalent of Esun is far better, I would recommend the second one for a similar purchase.

Very good quality but you need to learn it well!
In the first phase, print at least -50% speed and something will happen...
