The build quality of this pellet grill is as good if not better than other pellet grills Ive seen. This grill is nice and heavy, but has sturdy rollerblade looking wheels. I've only done several cooks on it, but so far this has performed perfectly. The temp was easy to set, and the smoke flows nicely from the chimney. There is a felt gasket on the lid to keep a better seal, thought that was a nice touch! I haven't messed with all the features or the app too much, but will soon.
