Our take
Hamilton Beach 31138 is a compact three-mode oven with a maker-listed four-slice or 9-inch-pizza fit, a 30-minute timer, and published outside dimensions. It is a stronger choice when those stated limits match than when larger measured cookware is needed.
For buyers whose four-slice or 9-inch pizza need fits the exact page's stated ceiling..
Not for buyers who require six slices, a larger pizza, 9 by 13-inch fit, full numeric temperature settings, or a known side/rear clearance.

What the features mean for you
A clear published fit reference
Hamilton Beach's exact 31138 page identifies a stainless-steel four-slice toaster oven and lists four toast slices or a 9-inch pizza. Those statements are useful when the food you usually prepare is close to that size. They do not establish a 9-inch-square pan, a 9 by 13-inch dish, or the opening dimensions of the cavity. The published figures are fit references from the maker page, not a measurement of every pan a shopper might own. If your cookware is unusual, compare its actual width and depth with the unit before deciding.
Three familiar modes and physical controls
The page names Toast, Bake, and Broil and describes adjustable temperature. The linked Use & Care guide includes 31138 in its model group and shows a Function/Temperature knob, an ON indicator, and a combined Toast Shade Selector/Timer. Toast uses the high rack and shade setting; Bake uses the low rack or pan and calls for a five-minute preheat; Broil uses the high rack over the bake pan. The guide does not give a complete numeric temperature range. The 450°F instruction is a first-use burn-off step, not a maximum setting.
Timer claims should follow the exact source wording
Hamilton Beach lists a 30-minute timer with automatic shutoff and a ready bell on the exact page. The grouped guide also describes selected-time or ON operation for Bake and Broil and directs the user to turn the selector Off and unplug after those routines. Do not extend the maker page's timer statement to every possible ON cycle. The guide also says not to leave Toast or Broil unattended and keeps food at least one inch from a heating element. That one-inch figure is internal cooking clearance, not spacing from the wall.
Outside dimensions are not a clearance rule
The manufacturer lists the outside body at 7.8 inches high, 15 inches wide, and 11.89 inches deep. The guide's electrical table rates 31138 at 120 V, 60 Hz, and 1,050 W. These details help with a footprint and supply check, but the packet does not identify a numeric side or rear clearance, under-cabinet use, cavity size, or tray dimensions. Leave those details open rather than translating outside measurements or the internal food gap into a placement threshold. Confirm the actual counter arrangement against the exact manual.
Keep the historical offer separate
The saved row carries a historical ASIN, but the manufacturer page and guide do not establish that the old identifier maps to a current Amazon listing. The customer page therefore searches Hamilton Beach 31138 by exact model code and adds the required tracking tag. The source-backed advantages are the stated four-slice and 9-inch-pizza fit, timer, modes, and outside size. A current price, stock status, seller condition, or review summary is not part of this assessment. Use the search destination to check the current offer and compare its model number before purchase.
What else to compare
Compare Cuisinart TOB-1010MB when you need a documented 11-inch pizza fit, or CFO-BB102 when its separate manual controls and mode-specific heat matter more.

The decision
Consider 31138 when four slices or a 9-inch pizza matches your routine. Confirm larger cookware and counter placement because those limits are not published.
