I ordered the 1502 and while the week long wait was agony it was finally delivered the other day, I got it all unpacked and plugged in. I cant believe how fast it heats up and the button to automatically level the turning racks, oooooh! hahahaha, ok so besides being totally impressed with the buttons it seems very easy to use and it can hold A LOT of eggs, I just cant wait to see if I get better hatch rates that I did with the hovabator. I have never been happy with the hatches I got from the hovabator even though I had the fan, got the turner and read everything I possibly could on hatching eggs I usually only got about 50% hatches a couple times I got 85% with my own mutt eggs. I had 8 eggs in the hovabator already on day 18 so I put them in the sportsman hatcher, due on sunday!! I also put about 20 or so Maran and Phoenix eggs from my own hens to test with. And of course being addicted, after finding this forum and more importantly the classifieds section I have about 40 eggs or so on the way, lol! I cant wait for some chickies!
