Quick Answer: Sam’s Club’s private-label Member’s Mark brand sells two unrelated-in-quality pizza ovens: the 12” Portable Rotating Gas Pizza Oven ($149.98-$199.98, also on Amazon, no membership needed) and the 16” Rotating Gas Pizza Oven ($229.98-$299, Sam’s Club-exclusive). Both claim 900°F, but independent testing by Pala Pizza Ovens found the 12-inch model only reached 755-775°F after 50 minutes with a weak flame, while owner reviews of the 16-inch model back up its 900°F claim and describe 60-90 second bakes that compare favorably to an Ooni. If you’re going to buy Member’s Mark, buy the 16-inch — and budget for the Sam’s Club membership it requires.
Sam’s Club stocks name-brand ovens too, including the Ooni Koda 2 Max and Ooni Karu 2 Pro — but Member’s Mark is Sam’s Club’s own house brand, the same relationship Nexgrill’s Ora line has with Costco. Unlike that comparison, though, the two Member’s Mark models genuinely aren’t interchangeable in quality.
Member’s Mark pizza ovens by the numbers
- 755-775°F: the actual temperature Pala Pizza Ovens’ independent test recorded on the 12” model after 50 minutes of preheat — well under Sam’s Club’s own 900°F-in-15-minutes claim for the same oven.
- 63.9 lb: the 16” model’s weight per Sam’s Club’s own spec sheet (26.6”L x 23”W x 13”H) — more than three times a typical 12-inch portable oven, reflecting its larger stone and fully insulated body.
- $70-$150: the price gap between the two models depending on sale pricing — the 16” runs $229.98-$299 against the 12“‘s $149.98-$199.98, but the extra money buys a stone that actually hits its rated temperature.
- Membership-exclusive: the 16” Rotating Gas Pizza Oven is sold only through Sam’s Club, which requires a paid membership (currently starting around $50/year); only the weaker 12” model is available membership-free on Amazon.
Two ovens, one brand name — they don’t perform the same
Both Member’s Mark ovens share the same basic formula: propane-fired, a motorized battery-powered rotating cordierite stone, and a bundle of included accessories. That’s where the similarity ends. The 12” Portable Rotating Gas Pizza Oven includes a 12” aluminum peel, a 4” stainless steel cutter, and an RPET all-weather carry case, and runs off two D-cell batteries for its rotation motor — a genuinely portable package on paper. But per Pala Pizza Ovens’ hands-on test, the flame is “way too weak,” the stone measures a thin 3/8 inch with poor heat retention between bakes, and the unit never got close to its advertised 900°F ceiling even after a 50-minute preheat.
The 16” Rotating Gas Pizza Oven is a different story. It ships fully assembled with a 16” aluminum peel, a 4” cutter, a 10”x6” cast iron griddle, and an all-weather cover, and Sam’s Club rates it to 900°F within about 15 minutes on a robust 304 stainless steel burner. Owner reviews back that spec up, describing 60-90 second bakes and comparing the rotating-stone performance favorably to an Ooni — a genuinely different tier of oven despite the shared Member’s Mark name.

What you actually get
Member's Mark 16" Rotating Gas Pizza Oven
- Reaches its claimed 900°F in around 15 minutes on a 304 stainless steel burner, backed up by owner reviews rather than just the spec sheet.
- Ships with a 16" peel, cutter, cast iron griddle, and cover — more included gear than most name-brand ovens bundle at this price.
- One recurring complaint: the included aluminum peel's holes can catch higher-hydration dough during the launch — pair it with a solid wood peel if you bake Neapolitan-style dough.
Sam’s Club membership not worth it just for a pizza oven? Try Amazon Prime free for 30 days instead and get the 12” model (or a name-brand alternative) to your door in two days, no warehouse card required.
Member's Mark 12" Portable Rotating Gas Pizza Oven
- The only Member's Mark oven sold outside Sam's Club — available on Amazon in black or red with no membership required.
- Independent testing by Pala Pizza Ovens measured real bakes around 755-775°F, roughly 125-150°F short of the advertised 900°F, with a thin 3/8" stone and a weak flame.
- Best treated as a budget backup or occasional-use oven, not a replacement for a dedicated portable like the Ooni Koda 12.
Who should actually buy one
- Buy the 16” Rotating Gas Pizza Oven if you already have (or are getting) a Sam’s Club membership and want a rotating-stone oven that genuinely hits its temperature claim for well under $300.
- Buy the 12” Portable only as a budget, occasional-use backup — not if you want an oven that reliably reaches Neapolitan-range heat, since independent testing found it falls well short.
- Skip Member’s Mark entirely and buy an Ooni Koda 12 instead if you want a proven ~950°F ceiling, a bigger accessory ecosystem, and don’t mind turning the pizza by hand instead of using a motorized stone.

The bottom line
Member’s Mark isn’t one pizza oven, it’s two — and only one of them is worth buying. The 16” Rotating Gas Pizza Oven backs up its 900°F claim with real owner results and undercuts an Ooni Koda 12 on price while bundling in more gear, making it a genuine budget alternative if you already have Sam’s Club access. The 12” Portable is the one to be skeptical of: independent testing found it running 125-150°F cooler than advertised, and while it’s the only Member’s Mark oven you can buy without a membership, that convenience isn’t worth settling for an oven that can’t hit real pizza-oven heat.
