I have tried 5-6 different PETG filaments ranging from €12 to €30 and I didn't have any printing issues with any of them. The specific one from Esun prints perfectly at 240°C, 80°C, layer 0.3. No warping at all and negligible shrinkage. I give it 3 stars simply because it is almost 50%+ more expensive than other filaments without offering anything special.

I have been using it for years and it was okay. Now, however, the latest batches have a paper roll instead of plastic, for some reason they are so wet from the factory, where almost half of the roll is useless and the rest prints better, but still has a lot of stringing. These issues didn't exist in the past.

Overall, I am very satisfied with eSun filaments, including this one. They consistently exhibit the same quality and characteristics in every batch. Once you find the appropriate temperature settings, cooling, etc., everything is consistent. After my own observation, eSun PETG should not exceed 235°C as it becomes brittle afterwards. Additionally, I print with a brim and a bed temperature of 80°C.

If you find the right setting, it produces pretty good results, but it gives me the impression that it absorbs moisture faster than other brands, so if you get it and don't work with it quickly, you may have issues with the prints
