Pros & cons

Masterbuilt 710 WiFi Digital Electric Smoker

  • ✓Real WiFi rather than Bluetooth, so the cook is visible from anywhere with a connection, not just the back yard
  • ✓Four-probe support is unusual at this price — enough to monitor a full rack load individually
  • ✓Side wood-chip loader is retained, so smoke can be topped up without dropping cabinet temperature
  • ✓Narrower 22-inch footprint than the 40-inch model while keeping four full racks, which suits a tight patio or balcony
  • ✓Fully insulated body plus thermostatic control holds a set temperature within a few degrees for 12-plus hours unattended
  • ✗710 sq in is 260 less than the 40-inch model at the same $350 price — you pay the difference in connectivity, not capacity
  • ✗Still capped at 275°F, so skin never crisps and there is no sear stage
  • ✗App reliability is the weak point of every connected cabinet in this class; a wired backup thermometer is still worth owning
  • ✗1-year warranty, and the controller is the component most likely to fail
  • ✗Chip tray gives thinner smoke than charcoal — expect a pale smoke ring compared with a drum or bullet

Masterbuilt 40-Inch ThermoTemp XL Propane Smoker

  • ✓The ThermoTemp thermostat regulates the burner automatically — the main reason to pick this over a manual-valve propane cabinet
  • ✓375°F ceiling is 100°F above the electric cabinets, which is enough to actually crisp chicken and turkey skin
  • ✓Runs off a standard 20 lb propane tank with no electricity, so it works at a campsite, a tailgate or during an outage
  • ✓960 sq in over four racks matches the 40-inch electric for capacity
  • ✓Fully insulated body plus gas heat recovers temperature far faster than electric after the door is opened
  • ✓Side wood-chip loading means the door stays shut through the smoke phase
  • ✗Propane cabinets are the least precise of the automated smokers — expect ±25°F swings even with the thermostat
  • ✗No probes, no app, no digital readout; the door-mounted dial thermometer is the only feedback
  • ✗A 20 lb tank runs roughly 18–24 hours at smoking temperature, so long cooks need a spare tank on hand
  • ✗Wind affects the burner more than it affects an electric element — a sheltered spot matters
  • ✗1-year warranty, and the gas valve assembly is the usual failure point
