What’s the difference between the Brinsea Ovation 28 Advance and Rcom 20 models?

The first difference between the Ovation 28 Advance and the Rcom 20 Max and Pro is the egg capacity. The Ovation 28 holds more eggs; up to 28 hen-sized eggs or equivalent. The Rcom 20 Max and Pro models can hold up to 20 hen-sized eggs, or equivalent.

The other difference is the that both the Rcom 20 Max and Pro have a humidity display and automatic humidity control, whereas the Ovation 28 advance has a humidity display, but the humidity must be controlled manually. Finally, the Rcom 20 Pro has a ‘species selector’ feature and specific settings for egg-turning; both of which are unavailable on the Ovation 28 Advance.
