An outdoor electric oven (wood pellets add smoke flavor only) that bakes very good no-turn pizzas and also smokes and roasts. It tops out at 700°F, isn't built for back-to-back party pies, and owners report control panels failing after a year or two.

Top complaints

  • Control panel and buttons fail

    Many 1-star Walmart reviews describe frozen screens, dead membrane buttons or control-board failures within about one to two years, sometimes just out of warranty. Wirecutter also mentions online reports of it breaking mysteriously.

  • Lower heat, slower pizzas, limited batches

    It maxes out at 700°F. Serious Eats found it slow to preheat and a few minutes per pie; Tom's Guide timed 5-7 minutes for fresh pies. Wirecutter notes Ninja advises against more than four pizzas in a row.

  • Small capacity, short cord, weather exposure

    Tom's Guide could cook only one item at a time, and the 4.5-ft cord meant using an extension cord. A Walmart reviewer says it is not waterproof and water can reach the electronics.

What owners love

  • Surprisingly excellent pizza

    Wirecutter's Neapolitan pie took about 2.5 minutes and was 'just as good' as the Breville Pizzaiolo's, which costs twice as much.

  • Hard to burn, beginner-friendly

    Serious Eats found its steady, lower heat much harder to burn pies with. Tom's Guide calls the presets and smoke box foolproof.

  • Versatile smoker and roaster

    Amazon shoppers praise its pizza and BBQ results and smoky taste; Tom's Guide smoked wings and roasted shrimp in it.

Good for
  • Hands-off pizza with no turning or flame
  • Smoking wings and roasting outdoors in one box
  • Beginners who don't want propane

Scores (tap for why)

  • Pizza results3.5
    Why 3.5?Wirecutter says its pizza rivaled the Pizzaiolo's, but Serious Eats says it can't do true high-heat Neapolitan pies.
  • Heat-up & recovery2.5
    Why 2.5?700°F max, about 30 minutes to heat the stone (Wirecutter), and no more than four pies in a row per Ninja.
  • Ease of use (turning, learning curve)4.5
    Why 4.5?Comes fully assembled, has presets and needs no turning; Serious Eats says its steady heat makes it much harder to burn pies.
  • Size & portability3.5
    Why 3.5?32.4 lb per Tom's Guide and Serious Eats (Ninja lists 49.38 lb), and it needs an outlet with a short 4.5-ft cord.
  • Build & durability2.5
    Why 2.5?Walmart owners report control-board and button failures and water intrusion; Ninja's page lists a 1-year limited warranty.

What experts say

  • Wirecutter (NYT): Worth considering as a versatile outdoor electric oven: pizzas rivaled the Pizzaiolo, but it's small, limited to about four pies in a row, and has online reports of breaking.
  • Serious Eats: Best pellet-flavored oven: steady heat and a lightly smoky taste, but slow to preheat and not for ripping-hot Neapolitan pies.
  • Tom's Guide: 4.5 stars: a user-friendly crowd-pleaser that smokes, roasts and makes pizza; the cons are small batches, a short cord and lower heat than dedicated ovens.
