This morning I ordered a Maverick 733 this morning from Amazon. Said it should be here by 9pm today.
Confirmed it is a bad probe on my iGrill. The probes feel cheap, so no surprise. I like the iGrill, love the interface and having it on my phone. But gosh, make a quality product, not one that just looks nice.
I'd really like one that works via Wi-Fi, not Bluetooth. Now if I could get my Nest Thermostat to monitor and control my Smoker:)
