I purchased this for my smoker more so than for my actual grill.  I love that it does need to be used in conjunction with weber grills or smokers.  I smoke a lot of meats and cheeses and this weber is perfect.  It is so far super accurate on the temperatures and it charges and connects to either Bluetooth or Wifi super easy.  I love the convenience of being able to have the app right on my phone.  I would highly recommend it to anyone who is looking for this type of thermometer.  It is very versititle!
