I purchased a pitmasterIQ 110 unit a bit back due to a recommendation from a friend. Now that I'm seeing all of these reviews about how terrible their customer service, along with my own experience, I regret buying it. When I first got it <2 months ago, the temperature that the pitmasterIQ reported was within about 5 degrees agreement with my ThermoWorks thermometer. Over the course of the two months I have found it getting further off, to a point yesterday where it was saying the temperature was correct (set to 225), yet my ThermoWorks was saying it was 175 and my weber smoker temp gauge (not super accurate, but usually within 10-20 degrees of my thermoworks) was saying it was 190ish. I put a second thermometer in there and it was telling me the temp was 173. So, both of my nicer, digital thermometers agreed it was about 175, yet the blower said it was 225. I emailed pitmasterIQ about it and asked if I could calibrate it, or why it would lose its calibration like this in <2 months. The probe is clean, hasn't been subjected to temps over ~275, and has never gotten wet. There's no reason for it to already be broken. Their CS department wrote back and merely said "you can't trust other thermometers, we have already tested them and found that to be true". Sure, let's ignore for a second that PitmasterIQ's own website has multiple videos of them using some cheapo Maverick thermometer to validate the claims of their own product, but my $140 ThermoWorks unit can't be trusted. Yeah, right, okay. After going back and forth, their CS lady (Barb) said the best they could do it have me send in the unit and have them test it. It's a friggin $10 probe.. I'll just buy another damn one rather than mail them this crap and wait for their test assessment to ultimately conclude I'm wrong. Eh, maybe I'm needy, but in this day and age I'm used to customer service that actually wants to help answer your questions, resolve your problems, etc. Telling me that their unit is right and my stuff is wrong is just such a terrible approach. Furthermore, no assistance in whether or not it can be calibrated, why it maybe lost its calibration, or anything of that sort was offered. Merely a "ship it back to us, on your dime, so we can test it." blowoff. I asked her multiple questions and every response was a one sentence reply stating either that their product was right or that I could ship it back to them with a note. These guys sincerely do not give two shits about whoever buys their products, that much appears evident.
