I have the octo 20 advanced, and it's a dream to incubate in. Holds temp like no other - you just KNOW it's spot on, always. The turner works great, I've not had a single issue with it, other than the temp does read lower than it actually is. I sent it back to the mfr. twice to have it recalibrated (which they did for no charge), but it still read 1.5 degrees lower than the actual temp. - but, once I figured that out, I just increase the temp. & haven't had any problems. I don't think you can change the temp. on the Eco, but I could be wrong - I think it comes preprogrammed to stay at 99.5.
