As some of you may know I bought a Pitmaster IQ 110 a few weeks ago and have had nothing but problems with the unit so I ended up shipping it back. The company just sent me an e-mail saying that they received the 110 and tested it out. They said there was absolutely nothing wrong with my unit or the probe and that they could either send it back to me or offer a 50% refund. I opted for the refund. The 110 is an extremely simple unit to use and I did everything I was told to do and then some, but I had the same results each and every time.
I burned through three 23 pound bags of Kingsford doing six test cooks with the 110. My WSM leaks a good bit from the access door and around the bottom of the lid, but then again so do most WSM's. As a matter of fact I don't know of many smokers that are truly 100% air tight, but apparently they need to be for the 110 to work properly. This still doesn't explain why the fan would continue to run almost constantly resulting in all of the charcoal catching fire.
One would think that when up to temp the fan would just barely run to keep the fire going. Anyway, a lot of people own these units and are completely happy with them, but for some reason it didn't work out for me so I ended up wasting some money. Just remember folks, you get what you pay for.
