I felt compelled to share my experience with GMG.
I purchased a Davy Crockett December 2016 and have used this machine nine times. So far I've had to replace the mother board and the ignitor. Dealing with their customer support couldn't be more painful. You stand a 1% chance of someone answering the phone, so leaving a message is your only option. The problem with this is by the time they call back you may not be at your grill for the troubleshooting needed to get your machine running. When GMG sent me the replacement parts needed to have my grill operate as intended they sent the wrong parts. So now i have to call customer support, leave a message, and go through the whole process, AGAIN!! One of the reasons i purchased this GMG was the WIFI capability. After doing the firmware updates my connectivity was intermittent at best. So if you experience trouble with the app you need to call GMG app support, which can only be of service in the afternoon PST. App support will be as easy to reach as technical support, leave a message! As for the replacement ignitor, as you may have guessed, it was for a different grill. So you know what i had to do. When they finally called me back i asked how to replace this ignitor. I was instructed to go to the GMG website to watch the video demonstrating how to do the replacement. We i finally received the ignitor, with no installation directions, that was designed for my grill, it didn't look like the one i just removed. The replacement part was almost three times longer then the one i just removed. So, I watched the video again just to make sure i had the right ignitor. I did, however it was much longer. Can you see where this is going?? I had to call technical support AGAIN and wait for a return call. When they called back i explained the situation and was wondering if i had the right part. Turns out they have changed the ignitor cable to a longer version. This was the last straw for me!! Keep in mind that i've used this grill 9 times and it's less than 7 months old.
Based on these experiences I would not recommend a GMG to anyone. I have since purchased a Yoder smoker.
