What we would actually buy One bullet. It tells you the slicer is green and that the thickness adjusts. Seventeen dollars, and nothing else on the page at all — no thickness, no steel, no guard, no weight.
What the maker puts in writing
“Contains (1) PrepSolutions Adjust-A-Slice Mandoline in Green – adjustable slicing thickness for all your prep needs.”
That is the entire listing. One bullet, on a $17.14 product, in a category where the specification genuinely matters.
What is not on the page
No hand guard. This is the omission that counts, because a mandoline is the commonest source of serious cuts in a domestic kitchen. The blade is fixed and razor sharp, and the injury comes at the last slice — when what is left of the potato is too small to hold and your fingertips go over the edge.
At least eleven of the eighteen listings on this shelf describe a holder or guard. The best go further:
Gramercy — includes cut-resistant gloves, the only listing that does
Joseph Joseph — three named grip styles: pinch for small, center for round, flat for long
Fullstar — steel-tipped guard rather than plastic, and says why
Ibergrif — a blade lock for storage and cleaning
OXO Precision — an automatic, height-adjustable holder that stores underneath
No thickness range, and no number of settings. Where this shelf publishes:
Benriner — a dial, 0.5 to 8 mm (0.02 to 0.31 in) — the only one below 1 mm (0.04 in)
Mueller Austria — a dial, 1 to 9 mm (0.04 to 0.35 in)
Fullstar — four clicks: 1, 2, 3, 4 mm (0.16 in)
OXO (two models) — 1, 2.5, 4 mm (0.16 in) · Ibergrif — 1, 2, 4 mm (0.16 in)
No blade steel. Gramercy publishes 4CR15, Fullstar 420 — the same hardenable martensitic family, which is the right one for a thin fixed edge.
No blade count. No julienne. No weight — the shelf runs from 70 g to 1,324 g, which is the difference between a handheld and a bench unit. No dimensions. No slicing surface width — only Benriner publishes one, at 2.5 inches, and it is what decides whether a large potato fits across the blade. No dishwasher statement — four listings here specify top-rack, which is the right qualification for a plastic-bodied tool. No warranty.
What to buy instead
Four handhelds cost less than this and publish far more:
Fullstar, $14.98 — four thicknesses in millimeters, built-in julienne, 420 stainless, steel-tipped guard.
Joseph Joseph, $14.98 — three named grips for three produce shapes.
Ibergrif, $15.99 — three thicknesses, and the only blade lock on this shelf.
OXO Good Grips, $18.85 — 1, 2.5 and 4 mm, and the window that shows what you have sliced.
For a bench mandoline, Benriner at $29.99 publishes the widest thickness range here and the only slicing surface width.
The one thing in its favor
PrepSolutions is an established kitchen-tools brand, and the slicer is adjustable and green.
Whatever you buy on this shelf, buy a cut-resistant glove with it. Gramercy is the only listing that puts one in the box.

The questions that come in
Does it have a hand guard?
The listing does not say, and on this product that is the omission that matters. A mandoline is the commonest source of serious cuts in a domestic kitchen: the blade is fixed and razor sharp, and the injury comes at the last slice, when what is left of the potato is too small to hold and your fingertips pass over the edge. At least eleven of the eighteen listings on this shelf describe a food holder or guard of some kind, and the best of them go further — Gramercy includes cut-resistant gloves, Joseph Joseph supplies three grip styles for different shapes, Fullstar fits steel tips rather than plastic, Ibergrif adds a blade lock for storage. This page mentions none. Assume one is in the box, and buy a cut-resistant glove separately whatever you choose.
What is actually missing?
Everything the rest of this shelf publishes. No thickness range and no number of settings — where Benriner publishes a dial from 0.5 to 8 mm (0.02 to 0.31 in), Mueller Austria 1 to 9 mm (0.04 to 0.35 in), Fullstar four clicks at 1, 2, 3 and 4 mm (0.16 in), and OXO and Ibergrif three each. No blade steel (Gramercy publishes 4CR15, Fullstar 420). No blade count, no julienne, no weight (the shelf runs from 70 g (2.5 oz) to 1,324 g (46.7 oz)), no dimensions, no slicing surface width (only Benriner gives one, at 2.5 in), no dishwasher statement — four listings here specify top-rack — and no warranty. The single bullet gives you a color and the word "adjustable".
What should I buy instead?
Any of four handhelds that cost less and tell you more. Fullstar at $14.98 publishes four thicknesses in millimeters, a built-in julienne blade, 420 stainless steel and a steel-tipped guard. Joseph Joseph at $14.98 publishes three named grips for three produce shapes. Ibergrif at $15.99 publishes three thicknesses and the only blade lock on the shelf. OXO’s Good Grips handheld at $18.85 publishes 1, 2.5 and 4 mm (0.16 in) and the window that lets you see what you have sliced — though it, too, mentions no guard. If you want a bench mandoline rather than a handheld, Benriner at $29.99 publishes the widest thickness range here and the only slicing surface width.
