Weber has always had great products. The I Grill 3 is intuitive and works well. The only downfall is the range. It's not very far. It reconnects quickly but you can't move more than 15-20 feet away.
Initial review as using it only for a couple of weeks so far. Winds up being quite accurate. Food comes out cooked as desired. Bluetooth phone notification very handy. Can do other things related to meal or otherwise and get notice when food is about to be done. So far, so good.
A good splurge upgrade! Is this necessary? No. A regular meat thermometer works. Is it handy? Yes. Easy to set up, just follow the directions. Bluetooth will disconnect if you walk away too far. Easy to reconnect.
