✓It gives you real charcoal flavor with set-and-forget digital convenience - the fan-driven controller holds temp automatically like a pellet grill but burns lump or briquettes
✓It's wildly versatile, going from a 225°F low-and-slow smoke to a 700°F sear, and the included griddle insert turns it into a flat-top
✓The gravity-fed hopper holds up to ~16 lbs of briquettes for roughly 8+ hours of unattended cooking
✓The digital controller and Masterbuilt app let you set and monitor temps and probe alerts from your phone
✓It reaches genuine searing temps that pellet grills can't, so steaks and burgers get a real crust
✓800 sq in of cooking space plus the griddle option make it a true do-it-all charcoal cooker
✓At ~$650 it's a lot of capability and charcoal flavor for the money versus separate grill and smoker
✓It heats up fast - charcoal lights and reaches temp quicker than a traditional charcoal smoker

✗Reliability is the big knock - the control board, fan, and temperature sensors are known to fail, sometimes within the first year
✗The thin sheet-metal body and gaskets leak and wear, so many owners reseal it to hold temps and protect the electronics
✗The 1-year warranty is short for a $650 cooker with so many failure-prone electronic parts
✗It still needs power for the fan and controller, so it's not a true off-grid charcoal cooker
✗Ash and charcoal management is messier than a pellet grill, and the hopper/firebox area needs regular cleaning to run right
✗Smoke flavor, while real charcoal, can be lighter than a traditional offset unless you add wood chunks to the hopper or ash bin
✗The app and WiFi can be glitchy, dropping the connection mid-cook like many smart grills
✗Rain and moisture can wreak havoc on the electronics and charcoal, so it really needs a cover and dry storage

✓Gravity feed plus DigitalFan holds a set temperature on real charcoal — the flavour advantage over a pellet grill without the fire management of a bullet
✓225°F to 700°F from one cooker: it low-and-slows and then sears steaks, which no electric or propane cabinet can do
✓17.6 lb hopper is larger than the 560 it replaces and covers a full overnight cook
✓Dual-wall insulation with a porcelain interior is new for this size and meaningfully improves cold-weather stability
✓App control with four-probe tracking at $800 undercuts most WiFi pellet grills of comparable area
✓Reversible cast iron grates give a proper sear surface on one side and a flat surface on the other

✗600 sq in is modest for the money — the 1050 gives 75% more area for $200 more
✗Gravity-fed ash management is messier than a pellet grill's: the ash bucket needs emptying and the chute can bridge with poor-quality lump
✗The fan and controller are mains-powered, so a charcoal cooker that needs an extension cord
✗1-year warranty, and the controller and fan are the components that fail in this design
✗Reaching 700°F burns charcoal fast — sear sessions drain the hopper far quicker than the 15-hour smoking figure implies
