I'm just curious because I see a lot of people saying that they're a must have, especially with the MES. I've got one in my shopping cart along with some applewood pellets and before I click 'buy' I had a quick question.... Why? I mean, I see posts saying that smoke is only important for the first few hours of your smoke anyways so what's the point of having something that makes smoke 10-12hrs? Isn't this overkill? Also, it means I need to buy special pellets and that will likely mean ordering online. I had the largest bag of pellets in my cart but I'm not really sure how long that will last so will I have to be ordering and paying shipping regularly? I can get wood chips local cheap at places like Home depot & Lowe's and my first (and only) smoke worked great. I guess I would just like to get some input before pulling the trigger on this to confirm that it's indeed the right move. It seems what I have already will work alright (once I accounted for the MES being like 40deg off from the display... arg) and I'm hesitant to start ordering things that just don't seem to make sense compared to the other things I'm reading. It seems adding a few tbsp of wood chips every 30min 6 times for the three hours of a smoke isn't the end of the world considering what most other types of smokers require in the form of baby sitting. Thoughts?
