Main differences between Colmi R06 and R11?

None of the Colmi rings are accurate with regularity, but even a broken clock is right twice a day. The sensors that go into the Colmi rings (and other clones) are so outdated that they no longer have any real commercial value...which is why the rings are so cheap.

Sheep in Wolves' Clothing? The List of Clones Masquerading as Legitimate Smart Rings MegaThread

As with all of the rest of the rings on this list, the Haale and Haale II are "white label" rings that have been licensed from China...in other words, a "clone." Clones are not copies, they are the same, identical devices. The specific device may vary with the examples above, but I will specify here
