I bought my brother one of these gadgets for Christmas but waited until a week or so ago to buy one for myself. I honestly didn't think I'd enjoy using something like this but can see where it would come in handy when it's 100 degrees outside. Standing over a grill in those conditions doesn't sound that great to me. These run about $80-100 depending upon where you buy and if you use a coupon (I did).
So I opened the box. It comes with two probes which you attach to the Bluetooth Thermometer device. You pair it to your phone after downloading the app.
I selected the setting for pork--but it put the internal temp at 145 and I like mine a bit more well done than that, so I manually over rode it and set it to 150.
Here it is once the two chops hit the grill.
It alarms you when there is 10 degrees left to go, and then again when your meat reaches your predetermined temperature.
And the done product. I was impressed cutting into it that it was done perfectly inside--not too dry and not undercooked either.
I put in about ZERO effort on checking or monitoring. Chops were cooked indirect on the BGE at about 400.
