I just purchased this a couple weeks ago,I liked it had big windows in it and that it had the temp and humidity gauges in the top,plus the plastic outer case.Well the temp does hold well at all,the humidity is off by 20%(that's a big deal),the smell of plastic is very strong,hope it does not bother the chicks.I have written to the company twice to ask questions and still have not heard form them,so customer service is not on the top of their list.I do like the windows.This will be my fist hatch,I have 42 eggs in, will candle on day 18 when I take out the turner.I wish now I had not sold my hova bator
