I have the BBQ IQ 110 right now. It really is the best tool on the market for temperature control. You really can just set it and forget it. Without that you have to constantly adjust temps and vents and there's no way you're cooking at a consistent temp. Plus the thermometer at the top on the lid is not at all accurate. However I notice that the sensors don't last for all that many cooks and then they go bad. And they're $20 a piece? Has anyone else experienced this and do you have any advice? I have done so many incredible cooks with it though.
