RCOM-20 standard or max incubator egg turning question

[GAQuail]

I'm shopping for a new incubator and one on the list is the RCOM-20 MAX (not the suro). The automatic turner on this incubator rolls the eggs instead of tilting them. It seems to me unless there is a way to adjust it that it would turn a small egg i.e. quail too far maybe even a complete 360 degrees which I would think would be counter productive. Any RCOM users have any thoughts on this?
Does the "Pro" model have an adjustment for this? Thanks!
