I know I am late to this party (thread), but I love my Thermoworks Signals. The Signals was a Christmas present to myself. The ability to monitor the pit via phone app or computer is a big plus for me, also I love that I can download data and graph the cook. I strongly considered the Smoke X; nice picture John K. I just added the Billows (20% sale) and now looking for a day above 35 degrees to try it. I did a months worth of searching and online reviews before making my decision. On the chopping block were Smoke X and FireBoard 2 (with and without Drive). Both strong contenders, in my opinion.
What sold me was repeated reviews stating Thermoworks was the experts on temperature equipment and I have a Thermapen Mk4.
