New to 3D printing, after having trouble keeping the bed level (or what I thought was bad just had to raise the nozzle temp) and had a lot of failed prints, I ordered them and they work However, in my case with the Ender 3 V2, I had to raise the Z-axis switch because the fully compressed platform was too high and scratched the platform plate. The Z-axis plate is a small switch on the left side as viewed from the front of the printer and is held in place by two T-nuts. You may need to fine tune the spacing and you may have 0.6-3mm less print area in height, but this can be remedied by lowering the model in your slicer of choice. Even though the nozzle temp solved my problem I'm still happy with it as nobody wants to level their platform after every print.
