you like them better than me course I have the 4200 and would never by another. candler is junk for dark eggs already had to replace turner motor tops don't fit right . also you have sticky chick so your humidity has been to high through the entire incubation and maybe your temp as well . before you hatch again calibrate you hygrometer . getting the humidity up has never been a problem .with mine . I run dry and it is still to high . the 4200s were analog I took them out and replaced them .. they are as good as any Styrofoam incubator I guess but they must be in a very stable environment to work well . I.E. a room with central heat and air would be best . I will not incubate in them again bought three older cabinet GQFs and incubated in the 4200 and hatched in one cabinet that is set up to hatch .In the same environment the GQF cabinet was able to drop humidity to 32% had to add water to get it up to hatch still only got a 50% hatch rate. but the damage had already been done in the farm innovators . but when I called them they said follow the instructions .several hundred dollars in shipped eggs later . I figured it out on my own and then came here to the byc and found I was right . but really glad yours are working for you . yea on the chicks hope maybe you get more
