This was one of the cheapest build plates I could find, and normally I wouldn’t have bothered buying except I have bought stuff from Biqu before and have been pleased with the result. They exceeded my expectations again. It arrived in excellent condition and undamaged and was double sided PEI surface, which is great for me. It also came with a magnetic layer to attach to my aluminum build plate but I already had one attached, so I didn’t use it. It stuck to my existing magnetic sheet very well and held prints with no additional surface treatments as if it were glued, while still printing at my usual print bed temps. In fact, I have to cool the bed 10 degrees C lower than usual to get the sheet to release, which for me is not a problem because I hate failed prints due to un anchoring from the build sheet. I am definitely will to buy again.
