I remember a while back somebody having problems with Maverick's customer service. A couple of weeks ago I did a smoke and thought my temps were off. I did a test with two of my Maverick ET73 probes and sure enough, both were off by about 15*. I emailed them and got a response back from Elizabeth who said she'd send me out two new probes and that if that wasn't the problem to send in the unit and they'd evaluate it there since there is no way to calibrate the units themselves. The probes showed up a few days later with an invoice that said "no charge" and both worked just fine. So kudos to Elizabeth and to Maverick for taking care of their products and their customers!
