This is so far hypothetical--both my coolers are working just fine. It interests me because I'm thinking of possibly buying a used OSC camera, and the main thing I'd worry about is TEC failure. And one of my cameras *is* 3.5 years old, though still going strong.
So--has anyone had their cooler fail and have it replaced by ZWO? If so, how much (approximately) did it cost in money and time? TIA for any replies.
