I've had good and bad. First time spent 80 dollars and got no fertile eggs. 2nd time my incubator got too hot(was a lg). I then found a great ebayer that sells alot of breeds on there. I think they are from arkansas. If you would like the name just pm me. ended up buying 8 times last year from her, not a egg broke and 80-100% hatch rates. I used on them my 1588.
