I can't understand why there are 4 memory banks here (I have 3). The thickness is 2 mm, and my old ones are about 1 mm by eye. Are the old ones so successful during operation?
Probably differences in memory setup as well.....but I can't imagine that it's much different.
As far as the old ones....keep in mind that the old ones have already been smashed due to the application, and may not reflect the original thickness properly.
