Maytag made this change 15 years ago. The small cubes on the flex tray were originally designed with a much smaller dispenser chute. The flex tray was made by Admiral and the motor heads were problematic. Maytag finally began making these obsolete and went to the common Whirlpool design of modular icemaker with a heated mold.
The cubes are only slightly longer than the old style and may fall thru fairly well, although there is more chance for jamming. All in all, it is an improvemnt over the flex-tray design which attracts mineral deposits.
