In 2013 I purchased three Black 60 units. Two were 2013 models, and one was a left-over 2012 model. The 2012 model has worked perfectly, and I'm still using it.
One of the 2013 models essentially quit working during the first year, and Covert was nice enough to replace it with a 2014 model. I don't think I've had any issues with that 2014 model Black 60.
However, my bad for not sending back my other 2013 Black 60 while it was still under warranty. It has periodically just failed to take ANY pics, even though it "appears" to be working properly during set-up. This week it totally died, providing me with only about 2 years of "intermittent" service.
Based on much of what I've read, Covert built their reputation on their 2012 models (along with their good customer service). But their 2013 Black 60 units were a crap shoot of very poor quality units. Unfortunately, this poor quality control seems to be a problem with most brands that are manufactured in China. They'll have a certain year model that is great, then the next batch of the same will be mostly duds.
