Our take
Oster 6299 is a manual-control option when the six-slice group identification and retailer-listed 12-inch pizza fit suit your planning. The maker's shared guide explains Bake, Toast, and variable Broil through separate Function, Temperature, and Timer knobs. It lists 120 V AC and four inches of spacing from surfaces and cords during use or cooling. The exact-code retailer also reports White with chrome accents and a 150–450°F range. Its convection wording conflicts with the maker manual's code list, and those disputed features are not treated as confirmed. This is a source-based review, not a hands-on test.
For buyers who value separate manual controls and accept retailer-attributed size and finish details..
Not for buyers who require verified Convection, Warm, a manufacturer-stated pizza diameter, measured dimensions, or a current offer linked to the historical ASIN.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The maker-authored manual includes 6299 in its six-slice toaster-oven group.
- Separate Function, Temperature, and Timer controls support distinct Bake, Toast, and Broil routines.
- The manual specifies 120 V AC and four inches of spacing during use and cooling.
What to weigh up
- No maker-stated pizza diameter or measured exterior/cavity dimensions are saved.
- The retailer title's Convection claim conflicts with the maker manual's list of supported 629x variants.
- Wattage, frequency, exact historical ASIN mapping, and current offer are unknown.

What the features mean for you
Keep model 6299 separate from the related 629x codes
Oster's P.N. 115718 Rev. B manual cover includes 6299 in its six-slice toaster-oven group. Best Buy also has an exact-code record for 6299, but the frozen historical ASIN is not linked to a current listing. Keep this code distinct from 6295, 6297, and the separate 006297-000-000 code. The shared manual is useful for operating procedures, while retailer details such as White with chrome accents and pizza fit remain attributed to that retailer record. Nothing in these sources verifies a current seller, package, or offer condition.
Three knobs divide the basic cooking tasks
The manual shows separate Function, Temperature, and Timer knobs and documents Bake, Toast, and variable Broil procedures. Bake uses the upper and lower heating elements; Broil uses the upper element and directs the user to leave the door at its first notch. Toast uses both elements, and the guide says it does not need preheating. These procedures provide a clear mechanical control map for ordinary oven work. The manual does not add an Air Fry routine or a digital settings display, and the more specialized modes described for related codes should not be carried over.
The timer separates timed cooking from Stay On
For timed Bake and Broil, the manual describes a timer that can be set through 60 minutes. At the selected endpoint, the oven rings and turns off. Stay On is a separate manual-stop setting rather than a longer timed cycle. Best Buy's exact-code record lists a 150–450°F control range, but that fact remains a retailer listing rather than a maker-published range in the reviewed manual. If a precise temperature threshold or timer behavior matters, check the actual controls and documentation for the unit being offered instead of assuming every related 629x model shares the same details.
Treat the convection description as a source conflict
Best Buy's title describes model 6299 as a convection toaster oven, while Oster's maker-authored manual says Convection is available only on 6291, 6293, 6295, and 6297. The manual also limits Warm to those listed codes. Because 6299 is not in that list, neither feature is credited as a confirmed operating mode here. A buyer who specifically needs convection or Warm should use a model with an exact-code procedure that resolves the discrepancy. This review preserves the conflict instead of transferring functions from 6295 or 6297.
Allow the manual's placement distance and check actual fit
The guide says to put the oven on an open, flat counter and leave four inches between it and all surfaces, including cords, while it is operating or cooling. It specifies 120 V AC but does not state wattage or frequency. Best Buy's exact-code record reports six slices, a 12-inch pizza, two rack positions, an auto-advance rack, and White with chrome accents; the maker manual does not give outside dimensions or a usable cavity measurement. Those retailer details can inform a preliminary comparison, but the available sources do not establish a 9-inch square dish, 9 × 13-inch pan, or exact current Amazon package.
What else to compare
Choose another reviewed model if you need a maker-confirmed pizza size, Convection routine, or measured exterior footprint.
Before you buy
Does the maker manual confirm Convection for 6299?
No. It lists Convection for other 629x codes but does not include 6299 in that list.
What timer behavior is documented?
Timed Bake/Broil can run through 60 minutes, ring, and stop; Stay On requires manual shutoff.
Is the 12-inch pizza fit manufacturer-stated?
The saved 12-inch claim comes from Best Buy's exact-code record; a manufacturer-stated pizza diameter is not established.
How much clearance does the manual require?
It calls for four inches from all surfaces and cords during use or cooling.
