Shoulda known with this one!!! LOL One yearS???? WarrantyI just bought the ADV 20 with turner, plugged it in, it got to temp and just held steady all day self adjust the temp. So far I love it! I also bought the ova-scope and this thing is amazing, looked at a brown egg (non-fertile) you can see all the way thru it, and you can rotate the egg,,,,,,,,,,I will set eggs Wednesday and i am very excited after using an old LG that I had to constantly adjust the temp on. Had it kill 24 shipped eggs, before I figured out the problem. I thought my grandson was messing with it (he's 2) Then I figured out we had an electricity problem, when the A/C was on during the day the bator wasn't getting full power, when we went to bed and turned the air off the bator shot up to 108,,,,,,,,,,,,,think I will love this Brinsea!!!
