Brinsea Maxi 24 EX Automatic with Humidity Control 24 Egg Incubator, Yellow

I've used other incubators, of the made-in-China variety that have digital control, egg turning, and even timers to turn this off on day 18 for lockdown, and supposedly had measuring instrumentation for the humidity and temperature of Japanese technology. But these failed to give me even a 50% hatch rate. So I finally decided to spend the money for a Brinsea, reported to be among the finest in quality. This Brinsea requires a modicum of knowledge of incubation techniques for proper operation, but when one knows what one wants to do, it will follow those instructions precisely. I haven't found it to have a day timer--no automatic shutdown of the egg turning process for lockdown. Lockdown must be initiated manually, including humidity adjustment. But when I set the incubation to 50% humidity at 99.3F, then up to 64% humidity for the final three days, it yielded a 100% hatch rate for me--the first such experience I have had. The peristaltic pump was difficult to set up for a first-timer, and I had to find a YouTube video to explain it, as I was still unclear from the manual's explanation, but once it was set up, all worked flawlessly. The egg turner must be set to a particular number representing degrees of rotation. This required marking the eggs and watching how far they actually turned based on their diameter in order to adjust the figure for ideal operation. The eggs are not continuously rotated in the same direction: they rotate to the left, then on the next cycle to the right, which is much gentler on the eggs' internal chalaza--likely one of the reasons for the higher hatch rate. I have not yet checked the temperature reading with a separate thermometer for calibration purposes. But two yields (so far) of 100% hatch rate leave me no question that it is already accurate enough--and one of those occurred even after the LCD screen indicated days where the temperature had exceeded the limit in the room, and a cold night draft had dropped it below its heating ability as well...yet the chicks survived this! Very happy customer...worth the price.
