This is a good transparent filament and quite easy to use. Works well at the normal temperatures for PTEG and I found it had excellent adhesion to a PEI bed, even when cold. Layer adhesion is good, print speeds are very good and the surface finish is what you'd expect from a high-quality PETG. It did arrive a little damp which I suspect contributed to it having more-than-normal stringing and the transparency not being the best but both were greatly improved by 12hrs@60C drying cycle. After drying the stringing was minimal and the transparency was normal for PETG
