Query: Review of Thermometer

I purchased the thermometer through Amazon which has always been a good experience shopping. I have used the device 3 times so far and 2 times the probes acted funny and the 3rd time the device just would not read to the wireless device. I e-mailed Maverick and they seem very nice but the device has not performed like it should. It states that it works 100 feet away. I am lucky if I get 30 feet away. The device has some very cool features and the 2 probes is what really sold me, since I do a lot on my off set smoker grill. If they would extend the wireless reach and make a better product I would buy again. Disappointed in this product,
