Green Mountain can't get out of their way. They have re-designed the heat deflectors that sit on the sides of the fire box. Only Mfg that feels the needs to have these. They are constantly updating their controller (continuous improvement or.........). Many owners having problems with ash on their food. I understand the Wi-fi is less than stellar in certain conditions.
Traeger,Camp Chef,Char-griller and Green Mountain are in the 500 buck range. Buyer beware in this price range.
Make sure you use a reliable dependable dealer that will help you make things right if you purchase a GMG,
Camp Chef is strictly sold through Camp Chef or big outfits. You will have to deal with CC yourself.
If you buy through a big box store on the Traeger you will also deal directly with Traeger. Find a local Traeger dealer and see if they will match the offer.
I have tested both GMG patio offerings and did extensive pellet testing on them for Simi Pellet Grills. I personally would look elsewhere.
One thing to keep in consideration is that Traeger and Green Mountain are probably the two biggest sellers in the pellet grill world. With that amount of units out being used there will be more defective units that you will hear about on the forums. However, they both do sell well so there are way more happy customers then unhappy.
