I am new to cold smoking. I have been into barbecue for over 10 years, and I cook some decent stuff on a DPP 60. When searching for a cold smoke generator I came across among other things the saw dust variant of the smoker I am reviewing. I called the company up, a guy named Todd answered. (nice to be able to speak with the owner when you call) I explained my needs to him and the size chamber I wanted to fill with smoke. He recommended a product he did not yet at the time have on his website, it's very similar to his others, but it uses pellets. He told me that he thought that one unit would be enough if lit from both ends to produce enough smoke for my size chamber. He also asked me to send pics of my pit. I did so and he quickly responded that two units may be needed. Me being a glutton asked him to send me 3 just in case. I am a typical American, if one can do it and two may be needed, three will get it done just right I asked this on a Saturday night. Sunday night I sent him the $$ he requested via paypall, and before I woke up on Monday he had shipped it out and had sent me a tracking number. Granted, I am a late sleeper so this may or may not be impressive, but less than 12 hours from payment to shipping impressed the hell out of me. A couple days later I receive the box and I am excited to unwrap my new toy. Upon opening I am impressed by the weight of the thing - it's tiny in size, yet has a good heft to it. Feeling it you can tell it was built to last. It's not bullet proof by any stretch, but I can not fathom a situation it could ever be in that would damage it. I could tell right away it would take me many years to break this thing, I am hard on stuff, my father once said to me "Boy, you could tear up ball bearings" Of course I could not wait to play with it, so I ran outside and loaded it with pellets. I hit it with my mapp gas torch for 10-20 seconds to get the pellets lit, and after 2-3 minutes of letting pellets burn, I blew them out and let her rip. One unit pours out a ton of beautiful blue smoke, when I walk outside, the whole backyard smells great!!! It also makes that smoke for a long time. He claims 11 hours, but he says that humidity plays a part. I live in a very humid area (southwest VA) and I was not able to get a full 11 hours. I clocked in at just a hair under 10 hours. I am more than happy with this. It's about as "set and forget" as I can imagine. So far I have used it for cheese, various nuts, hard boiled eggs, and salt. I was supposed to pick up 30 pounds of pork belly for bacon today, but my butchers order did not go as planned and I am now picking it up on friday. I can not wait to see how bacon turns out using this. Over all I can not say enough on how happy I am with my purchase, and the service I received. When I called Todd, this product was not available on his website. He told me that I could buy it and if I had any issues at all to send it back for a refund. About an hour ago I sent him an email that in part said "Keep the money, there is no way in hell I am sending this back to you" I have not bothered to take pics yet, as everything I have done so far is mostly playing with it. In a week or so I will do a detailed thread on the bacon I am making. I will update that with pics hourly on how far the pellets have burned in it, and just how much smoke it gives off.
