Reading through the posts here is my experience with
Brinsea ECO 20.
I bought my ECO 20 about 5 years ago.
Pluses: Much better than any styrobator.
So far very tough and reliable, no major issues.
Great run for your money.
Bottom (base) easy to clean and disinfect , but the top is another story (cleaning).
Minuses:
Humidity control can be a problem as most report, but this is typical for most small incubators due to inadequate evaporation area combined with small air volume.
Original
Brinsea Thermometer went off about 2 degree (lower) after few years of use. I replaced it with mercury therm of very close size.
Digital therm will sometimes give off readings, perhaps due to oversensitivity and again small air volume.
I also noticed temperature swings when tilting. After close examination it appears the top cover plastic has too much flex and likely allows some air leakage during swing.
My remedy for hatching is fitting medium thickness cotton sheet cut to size, on the bottom, bending it down to fit water wells, it allows me to get humidity as high as I want. Experiment with size of the sheet, make sure bottom 4 ventilation corner holes are not covered. You will need to add water almost daily using this method, but I am not worrying opening it, cause due to small air volume humidity snaps back in matter of minutes or even seconds when using extra evaporation help.
As any small bator
Brinsea 20 (at least mine) will not hold rock solid temp if the room temperature swings more than 5-7 degrees (day/night). Small adjustments needed.
Conclusion: I am overall satisfied, however lately I am using my
Brinsea 20 as a hatcher (what an irony huh?) cause I do weekly hatches, and my homemade cabinet bator has 2 standart turners for better eggs management And also it is more stable temperature wise in changing ambient air temperature.
There is no substitute for stability and inertia of greater air VOLUME, no matter how advanced and sophisticated electronics they put in those small bators.
