My 6000 is great! I had my first big hatch over the weekend but my hatch rate was low because of an error on my part. The Reptipro is holding temp great and is about 1 degree off from my thermometers and does much better in regards to the temperature difference between the top and the bottom ...My 5000 was 3-4 degrees of at times ! I just wish y'all would come out with a bigger model so when I need to upgrade to a larger capacity incubator I could stick the brand!
