The Masterbuilt MB20072918 is the tall version of the familiar digital cabinet smoker. It is aimed at people who smoke in batches: a few racks of ribs for a party, sausages and a pork shoulder on the same afternoon, or bacon and cheese for the freezer. Its defining feature is space. Masterbuilt quotes more than 970 square inches of cooking area, which is the most of any electric smoker in our comparison.

- The listing gives no temperature range or details of a water bowl.
Our take
What the cabinet offers
Amazon lists a cold-rolled steel body, four cooking racks, a removable grease tray, a locking door and an easy-access wood chip loader. Control comes from an adjustable thermostat and an electric timer, so the routine is simple: load chips, set the temperature and time, then let the element do the work.
That is a short list compared with some rivals. The listing does not mention a water bowl, a viewing window, an air damper or a meat probe, and it gives no temperature range. Those may or may not be present on the unit, but you cannot rely on them from this page alone.
Living with a 40-inch smoker
The cabinet measures roughly 65 cm wide, 50.5 cm deep and just over a metre tall, and it weighs 25.8 kg. It will sit happily against a wall or fence, but you will want a level, sheltered spot near an outdoor socket, because an electric smoker needs mains power for the whole cook.
Four racks spread over that height mean you can keep fatty cuts low and lighter food such as fish or vegetables higher up. The removable grease tray is the main cleaning job after each session, along with emptying spent chips.
How it sits against the 710 WiFi and 30-inch
The Masterbuilt 710 WiFi has a similar four-rack layout but roughly 711 square inches of space, a stated 38 to 135 °C range and an app that reports probe readings to your phone. The 30-inch digital with legs adds a window and an air damper. The 40-inch trades those extras for sheer room.
If you mostly cook for two, the extra height is wasted heat and storage space. If you regularly fill every rack, the larger box saves running two sessions back to back.
Check the plug before you order
This listing does not state a voltage or plug type. Masterbuilt models are sold in several markets, so confirm with the seller that the unit is the UK version rated for 230 V with a UK plug. Using a converter with a cabinet heater is not something to plan around.
Verdict
Buy the 40-inch Digital if capacity matters more than gadgets and you already know you like smoking food in quantity. If you want to monitor cooks from indoors, the Masterbuilt 710 WiFi is the better fit, and the 30-inch Digital with legs suits anyone who values a window and damper over extra rack space.
