Product review (4 stars): Slick
I broke the battery contacts in the unit I had so bought this replacement. Turns out I was able to fix the old one, so now I have two. This is great, one on each side of the house. I live on a lake so the temp is usually different in front and back. The Honeywell base allows up to 3 sensors, so now I have two and can easily see where to set up the grill.

Two complaints with these though. 1) They stop working before the batteries are dead. So even thought a battery tester shows it to be "good", and the LCD on the sender unit accurately displays the temp, I know I still have to replace them (batteries) when the base unit shows "---". 2) The battery cover should snap off instead of having 4 tiny screws. The heads are already shot from the first installation. Otherwise it's good.
