Product review (2 stars): Fill time (cube size) adjustment did not work
The ice maker works and the price is good but the lack of fill level adjustment is a deal breaker for us.

Yes, there appears to be such an adjustment but I don't think it's real.  I (and some others) have tried turning the plastic stud that is implied to be an adjustment for cube size (fill level) but it didn't do it.  And the provided user instructions make NO mention of any such adjustment.

I understand that some have turned down the water flow to their refrigerator and obtained satisfactory results.  In our case I had to turn down the water flow a lot to obtain proper level and that caused problems: 1) the water inlet to the ice maker was more prone to freezing/plugging with the lower flow rate, 2) the ice maker overflow caused the dispenser unit below it to freeze up, and 3) the flow rate to the water dispenser became unacceptably low.

This ice maker might work for you if overfilling does not become an issue.
