Query: Big Disappointment

Bought this for my husband for Christmas. The idea was that he could monitor the temperature inside the smoker AND the meat he was smoking, all from inside the house (less than 50' away.) Unfortunately, as soon as he was about 40' away from the smoker and just around the corner (still outside) it stopped working and he would have to reset everything. It did not work properly from day one. We thought we may have just gotten a bad unit and were going to ask for a replacement. Now we're told we can only get a refund - "replacement unavailable." Although we see that they are still for sale on Amazon.com (and $7 more!) I note other reviewers had to have one or more replacements. I recommend searching for a better brand.
