Review on 🖨️ Enhanced Printer Glass: 235mm x 4.0mm for Reliable Built-In Performance by Jerry Estrada

I didn't expect these panels to be anywhere near as flat as the ones I received. No ABL upgrade on my original Ender 3 and I've had the first perfect seed layers since I've had the printer. Be sure to research glass beds as some materials require special build plate preparation. I only print PETG so I always have a glass-based "PDG" layer that adheres well and is easy to remove. A few notes: Make sure you set the Z end stop as these boards are thicker than the original build surface. - DO NOT sand the build surface unless you are printing exclusively with standard PLA and no adhesives. - The grid and black background are drawn on the bottom of the plate, so they are NOT reversible.
