I have both the Big and Lil Chief smokers. I use 'em all the time.
One thing to remember is that it's not going to cook your food. You will need to finish cooking it with some other means. If you're doing ribs, pork butt, or chicken...you'll want to smoke it in the smoker for 2-3 pans of chips, and then finish cooking the food in and oven, or on the grill. The smoker just doesn't get hot enough to cook meat all the way through.
We got my Dad one for Christmas last year, and he uses it quite a bit. At 75 yrs old, it's pretty easy for him to smoke some ribs for a few pans of chips, and then finish them on the grill, or in the oven.
I use mine for fish, nuts, bacon, Canadian bacon, cheese etc....
To store it, install the front cover backwards....so the handle is on the inside of the smoker. Then it will fit right back in the box. I store mine like that in the garage, and it doesn't smell at all.
