I am totally impressed with the PEI sheet. I have mine attached with the high temp 3m double sided adhesive tape. No issues with prints sticking, every few prints or so, I also give it a light sanding with 2,000 grit sandpaper. I have been printing mine at 235 hotend, and 90 for the bed. If they get a 10x10 buildtak, I might have to try that sometime. correct me if I am wrong but they don't make that size yet.
