Query: Worked for a Couple of months then failed

I now have two different Maverick Thermometers. This and an ET-73. Each of them worked good for the first 60 days then quit. Their customer service is poor and the wireless technology they use is intermittent at best.I think I speak for the thousands of folks who have invested alot of time and energy into Eggs, Smokers, etc and I'd like to see a top quality wireless unit even if it is 3x as much up front.
