I have one, it's fantastic! It does let out some smoke during the process, so I put an exhaust fan in the window when I use mine, to make sure it removes the smoke. I also wrap foil around the end to help keep it in. I used to smoke chicken way back when, but no longer eat meat. I now use it to smoke tomatoes (very delicious) and may try mushrooms next
I bought all of the different types of wood chips to go with it. It uses a very finely ground wood, not like the usual you buy to go in a conventional smoker. I loved all but the alder wood. I bought them from www.famousfoods.com
I haven't tried them yet, but I recently bought some smoker bags that seal up and you use them in the oven. They are also made by Camerons.
