I've had the Auto Kamado for almost 2 years. It's easy to use & very efficient. I've done 15 hr cooks no problem. I broke the piece that lifts the grate & called for warranty. It took about 6 months to get it. 
Sometimes it doesn't start back up after pausing it. 
I just kill the power & reset it. It's a pain but there is no other way. I get an error sometimes when i lift the lid. I assume there's a short in the thermometer cable. I need to call to get that covered before the warranty lapses. 
Overall, it's great, BUT the electronics aren't as reliable as they should be. It has bugs. Otherwise, it would be a 5 star rating.
