Ok. First of all this is a pellet grill/smoker. They say its a grill, but since its convection heat you don't really get to sear your meat. I cooked up a steak when it was warm enough(in Michigan), but I seared it on the stove first.
Here are some bullets:
-The Green Mountain Grill must be plugged in.
-If the pellets get wet, they turn to sawdust. So keep it stored indoors. Or covered.
-It has a temperature range of 150 to 500 deg F.
-You set it like an oven and it self regulates the heat.
-Mine came with a temperature probe and remote control where I can adjust the temp and monitor meat temps from inside my house.
-The steaks I made tasted like they were coked over a camp fire pit.
-The pellets must be food grade, but are easy to get. The cost is about $0.50/lb and it is easy to get them in my small town.
-This thing cooks like a convection oven that has smoke. The lower the temp the more smoke it produces.
-I just want to restate that this does not sear meat.
-It cooks a really good steak.
-Ridiculously easy to use.

If you are spending the money and want a more versatile grill/smoker that will sear a steak you might want to look at a big green egg.
