200 bucks down the drain. After my 2nd hatch and only 28 or so days of use - it started beeping nonstop, and the temp got stuck on 140. The up and down buttons don't work. How annoying, thank GOD my 2nd batch hatched LAST NIGHT. Talk about the nick of time. It started doing this spontaneously this AM. I had some of my own eggs from sizzle/silkie incubating for a few days - they were free though. I spent a lot on my ebay eggs. And thank goodness they were done and hatched. Not that I care how much eggs are, but in general, it'd be heart breaking for this to have happened at day 20.
