A while ago I bought a roll of transparent petg "the filament" by spectrum. Wonderful, it printed great, shiny, smooth. I loved it.

Then I took advantage of the promotion on the Bambu lab website "4 rolls are discounted + free shipping" and I bought their transparent petg.

I opened the vacuum bag, loaded immediately in the printer and it strings and pops. Settings are correct as the slicer has a dedicated profile for this roll.

Their website says "warning: dry before using" - they mean that it comes already too moist from the factory?

I've found it varies from manufacturer to manufacturer as well as colour, some of the petg I've got has been chilling in my cabinet in the garage for at least 1 summer and it prints fine, just some stringing, other spools they're a mess right out the bag. Still worth drying filament, but more so stuff like nylon which is extremely hygroscopic.
