I have good prints and I have bad prints with my Build surface. It seems that they have to be adjusted to it their own G-Spot that your printer likes.

It also helps to clean the Bed with 70% alcohol just before you print. I like the build surface it Looks better than the old Aluminum bed surface.
However I still place Tape over the Build Surface as it is less forgiving than the build surface.

Video was made before I purchased the Build Surface, returned because it still works better on my 3D Printer.
