I bought the iGrill for the summer grilling season and first reviewed it then. Since then I've gotten a new iPhone, IOS 6, and the updated iGrill app. The app seems to do what it is supposed to do, nothing too fancy. Pairing with Bluetooth is always a pain. I do not have that problem with other Bluetooth devices, so it is not IOS, but the iGrill device that is a problem. The 400 degree maximum temperature makes it useless for keeping tabs on your outdoor grill. I put the meat on when my grill is at 550 degrees.
I have never attempted to determine the devices maximum range. But if it includes walls and other such obstructions obviously not anticipated by the vendor, it's closer to 40 feet. I'm currently a couple of walls and 30 feet away and have lost the connection.
The device itself is flimsy. Many have written that the stand is useless and indeed it is. I don't bother with it. Since acquiring the iGrill, two of the black screws holding it together fell out. I can't put them back in because there doesn't seem to be any thread in the plastic for the screws to hold on to. Just today, Thanksgiving day, I was replacing the batteries and the tabs beneath two silver screws behind the left battery broke off, taking the screws with them. The company should find better Chinese outfit to build this thing.
Since it is Thanksgiving, I hoping to measure the turkey's thigh and breast temperatures. Alas, one probe now thinks that ice water is 145 degrees, so I can only use the other. I suppose the probes are not dishwasher safe, although probes from other devices that I own are. So with tears in my eyes, I decided to place the working probe in the thigh and use a dial thermometer in the breast.
