Our take
The BLACK+DECKER FP4100B is an 8-cup processor with a stainless S-blade and a reversible slice/shred disc. Its maker lists a 450-W / 120-V motor and describes a bowl-first, lid-twist assembly. This is a practical middle-size profile among the published models: it offers more room than a compact chopper but does not meet the strict nine-cup threshold used for the large-batch finder path.
A shopper wanting an 8-cup household processor with both chopping and slicing/shredding tools, but not a 9-cup-or-larger bowl..
Not for buyers who require at least a 9-cup bowl, a separate small work bowl, a dicing kit, or a dedicated dough blade.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer identifies the FP4100B and states 8-cup capacity, 450 W, and 120 V.
- A stainless S-blade and reversible slicing/shredding disc cover two distinct prep styles.
- The documented bowl-and-lid twist-lock order is a concrete assembly detail.
What to weigh up
- Eight cups is below the nine-cup hard large-bowl threshold.
- The checked page lists one work bowl and no dedicated dough blade or dicing kit.
- The exact marketplace package should still be compared with the official model configuration.

What the features mean for you
Eight cups is a meaningful middle size
BLACK+DECKER specifies an 8-cup work bowl. That gives this model more room than a small chopper, while keeping it below the nine-cup cutoff that the category finder treats as large. A buyer preparing occasional family meals may prefer to compare it with larger machines and decide whether an extra cup changes the routine; the published number alone does not state usable fill for every ingredient. Because bowl size is a hard attribute in some paths, this model should not be described as meeting a requirement for nine cups or more. [bowlCapacityCups]
A blade and a reversible disc cover different jobs
The official page lists a stainless S-blade for chopping and mixing and a dual-sided disc for slicing and shredding. This gives the FP4100B more flexibility than a single-blade chopper, while staying short of a broader specialty attachment package. The page does not list a dicing kit, spiralizer, meat grinder, or dough blade. If those jobs decide a purchase, compare a model whose maker documentation names the exact tool rather than treating a reversible disc as a substitute. [sliceShred, dicingKit, doughBlade]
The assembly sequence is part of the model's design
BLACK+DECKER describes setting the work bowl onto the base and twisting the lid until it locks. That sequence is a documented design detail and helps buyers understand how the machine is assembled; it does not establish that operation is easier for every user. The bowl is one processor vessel, and the product page does not list a separate smaller bowl. The finder therefore does not give it credit for a second work bowl, even though the device can handle both chopping and disc processing. [smallBowl]
The maker gives a clear North American electrical rating
The official product page states 450 W and 120 V for FP4100B. This supports the exact-model North American-voltage attribute without borrowing electrical facts from a similar FP4200 or another family member. The maker page describes food preparation and contains no heating claim, so this is a conventional processor rather than an integrated cooking machine. These details distinguish supported compatibility from unknown package contents; a shopper should still check that the current listing carries the same FP4100B code.

The exact page matches the frozen model, but the package matters
The frozen candidate is ASIN B0841NBX4Y. The inspected Amazon page matches the FP4100B Easy Assembly title, and BLACK+DECKER's model page names FP4100B and its documented configuration. That permits a tagged direct ASIN link, while the review still describes the maker's stated model contents rather than asserting every seller bundle variation. Verify that the offer retains the bowl, S-blade, and reversible disc named by the official page. A renewed, bundled, or substitute listing should not automatically inherit this profile. [sliceShred]
Compare it with a true large-bowl alternative
The FP4100B fits shoppers who want an 8-cup bowl and both chopping and disc tools. KitchenAid's KFP1333 family is a different choice when a 13-cup main bowl, separate 4-cup bowl, adjustable slicing, reversible shredding, and a dough blade matter more. Those extra tools and capacity make the KitchenAid package broader, while the BLACK+DECKER has a simpler listed configuration. Neither description is a performance ranking; choose according to the bowl threshold and attachments you will actually use. [bowlCapacityCups, smallBowl, doughBlade]
What else to compare
Compare KitchenAid KFP1333 family for a 13-cup main bowl, a separate mini bowl, adjustable slicing, and a dough blade; it is a different capacity and tool configuration.
