Yeah, I’ve heard-tell and seen pictures… (Including PET just taking huge chunks of glass with it when parts are removed!!) But considering everything I’ve put it through-- like literally scraping all the glue residue clean with a razor blade after every several prints, and printing PLA, ABS, Nylon, TPU, TPE, PCL, PVA, PC, and even PETG on it --for a year and a half without so much as getting a scratch, it makes me wonder if the people having these problems maybe got ripped off and got low-quality borosilicate glass, or possibly something else altogether. Or maybe it’s a matter of thickness. A lot of the examples I’ve seen of damage have been with what looks like 3mm (1/8") thick pieces of glass, and a 6mm piece like what I have is far more substantial.

The metal build plate is good too, if it’s well-made and flat… Mine wasn’t, for example; It dipped in the center. (But they’re also going to undergo far more thermal expansion than even non-borosilicate glass.)
