Pros
- AmazingRibs: "Overall, performance of the ThermoWorks Thermostatic Controller Signals/Billows pair is very good", on a Weber Smokey Mountain
- Buy the thermometer now, add the $89 fan later; the Signals also drives the Billows from the cooker without a phone
- ThermoWorks prints the Signals' accuracy by band, and its warranty is two years
- Ball-valve kits for offsets, which most fan makers do not sell
Cons
- No open-lid detection, by AmazingRibs' test
- Billows needs a 12V supply or ThermoWorks' battery bank; the Signals battery alone lasts 16 hours
- The Signals' accuracy widens to ±5.4°F above 392°F, and Bluetooth reaches 95 ft line of sight
- No combined bundle: $338 for the pair from ThermoWorks (buy button coming soon); the Signals on Amazon is $259 alone
