First: this is a chopper
And a chopper is not a mandoline, which the listing never quite says.
A mandoline has a fixed blade in a flat runway. You slide the vegetable along it, one slice per pass, and the thickness is set by how far the blade stands proud.
A push-down chopper has a grid of blades in a frame. You put half an onion on it, bring the lid down, and the whole thing is diced in one movement into a box below.
The chopper is far faster for dicing and no use at all for thin even slices, because there is no thickness to set — you get whatever the grid gives.
This tool is both: two different sized chopper blades, 4 interchangeable blades for slicing, julienne & grating.
Buy it for the chopping. The Benriner and the three OXO units on this shelf are mandolines proper.
The container is the real argument
Free-up countertop space with the Food Container.
Dicing an onion with a knife leaves you with the second problem: getting it off the board and into the pan, which is where a third of it escapes.
A chopper dices directly into a lidded box. So you prep ahead, put the lid on, refrigerate — or tip the lot in at once.
The Mueller Pro-Series on this shelf has the same. The mandolines solve collection differently: OXO and Benriner hook over a bowl, and Mueller Austria has folding legs so it sits over a bowl or on a board.
Three claims that cannot be checked
“More restaurants use Mueller than all the others combined because of our quality”
No source, no survey, no period. On the chopping board shelf of this site, Farberware cites NPD Group and a measurement window for its market claim — nine years old, but cited.
“Another well marketed lower quality white/black model claims to be the original”
An attack on a rival that is not named.
“6 Awesome Blades For the Price of 4”
A value claim with no reference price.
None of that means the tool is poor — Mueller choppers are widely used. It does mean the page is selling confidence rather than specification, and the specification is where it is thin.
Twenty-four hours, by telephone

The only live-support claim on this shelf, and worth something on a tool with six interchangeable blades and a frame — the questions people have about these are assembly questions.
What is not published
No thickness in millimeters, where Benriner publishes a dial from 0.5 to 8 mm, Mueller Austria 1 to 9 mm, Fullstar four clicks and OXO and Ibergrif three each.
No blade grade — “high-qual[ity]”. Gramercy publishes 4CR15 and Fullstar 420, the same hardenable martensitic family.
No dishwasher statement, where four listings here specify top-rack — the right qualification for a plastic-bodied tool, because the bottom rack is hotter and warps it.
No warranty. And note the catalog records the brand as JANSKA while the product is a Mueller; the same applies to the Pro-Series on this shelf.
