We have a Green Mountain small one, previous model name I can't think of. Had it about 5 years has been great.
Couple things. Empty the hopper out after use. If you leave the pellets in they draw moisture and won't burn right.
You need to clean out ash in bottom if you are having problems getting it up to temp.
The cigarette lighter plug for auto use went bad and wouldn't give a consistent connection. I called Green Mountain and they sent out a replacement no cost, no questions. Great support.
Misting meat with apple juice or rum gives it a neat glaze
