While the PEI sheets are great quality and the instructions are well written(minus a few thing), It took me hours to replace the PEI surface. Not only was it frustrating, but its impossible not to get any bubbles to form under the sheet. I took my time and did everything I could think of but nothing worked. Now I have a build plate with multiple large bubbles and cant get them out. If I knew it was going to be this difficult, I would of just bought another Spring Steel Coated PEI Build Plate instead of wasting 5 hours to replace it myself. I really wish Prusa had a service in which you can send your old PEI coated sheet in and have them replace it for you. I would gladly pay for the shipping and for the fee to do so.
