straight glass will most likely need some kind of better surface to be reliable.
A cheap self adhesive sheet of pei is a good option.

The reason I'm so against creality and the ender series in particular - is that in the last two years, we have had more people with problems with ender3 printers on this forum - than ALL OTHER PRINTERS COMBINED.
Look at it this way. Josef prusa designed the I3 with dual z motors, direct drive extruder and side supports bed rails. Creality disgarded all those to save money, and it has resulted in a design with an awful lot of built in problems. This is not helped by their using dirt cheap components and having a virtually non-existent user support.

For every you-tuber who's rebuilt their ender, there are hundreds of poor souls out there who are just lost and have no clue how the make the damn thing work.
And it really annoys me that there are people out there recommending these things for first time 3d printer users.
