Our take
Nuova Simonelli describes the MDJ as a professional on-demand grinder with micrometric adjustment and flat 75 mm burrs. Its current product page lists a 1.6 kg hopper and up to 3 kg/day, and the maker brochure separates low- and high-speed versions with different grinding rates and electrical ratings. The brochure also documents two programmed doses for its described version; this is timed/programmable control, not weight dosing. A separate Simonelli USA listing for an MDJ OD Digit reports a 1.7 kg hopper and suggested 5 kg/day, so buyers should confirm the exact revision before relying on capacity, output or power figures. The historical Amazon page identifies ASIN `B07DGNSWVD` as the MDJ family and lists part number `NS-MDJ-Grinder VS`, but it does not establish a specific speed/electrical revision or expose a verifiable current offer. The maker's stated output is product documentation, not an independent result. This is not firsthand testing.
Professional espresso buyers verifying the physical MDJ version; unsuitable for scale dosing or unverified supply requirements..
A compact home setup or a hard capacity, daily output, wattage, dose-style or voltage requirement based only on the historical row. Check exact revision, counter clearance and unit nameplate first.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Nuova Simonelli's current page identifies a professional on-demand model with micrometric adjustment and flat 75 mm burrs.
- The current MDJ page lists a 1.6 kg hopper; the digital brochure documents two programmed timed doses for its described version.
- The maker documents distinct low/high-speed configurations, giving buyers version-specific facts to check against a candidate unit.
What to weigh up
- The row's part number does not select MDJ speed, revision, hopper, electrical rating or controls.
- The 1.7 kg hopper and suggested 5 kg/day belong to a separate MDJ OD Digit catalog entry; do not merge them with the standard MDJ page's 1.6 kg and up-to-3-kg/day statement.
- Programmed time and optional time-derived gram display do not measure dispensed grounds by weight.
- No current exact Amazon offer, independent output measurement, burr material, noise or retention is established.

What the features mean for you
Suitable use
A café or restaurant espresso-service comparison where on-demand operation, micrometric adjustment and a confirmed programmed-dose workflow are useful, after checking the offered MDJ revision and electrical supply. The MDJ line has distinct standard and SPEED versions, and the saved row clue does not identify the version, rating plate or current offer.
Limits and unresolved facts
Hopper size, daily-output statements, low/high-speed rate, voltage, wattage and dimensions differ by document or named version. The manual's MDJ SPEED variant has separate run/rest values from MDJ; do not transfer them to this historical part number. The time-derived gram estimate is not a weighing sensor, and the maker's output claims are not independent tests.
Questionnaire reasoning
Professional positioning, flat 75 mm burrs and micrometric adjustment support a model-family comparison. A mandatory two-programmed-dose workflow is supported only for a maker-described version; it cannot satisfy weight dosing. Treat 1.6/1.7 kg hopper capacities, 3/5 kg daily claims, low/high-speed rates and electrical ratings as document-specific. They cannot pass hard thresholds until the offered MDJ code and nameplate match.
Model-line controls and capacities
The manufacturer material describes MDJ as a commercial on-demand line with micrometric adjustment, 75 mm flat burrs and timed programmed doses on the described versions. Hopper and daily-use figures differ by version, and the standard and SPEED model facts must remain separate. Optional gram calculation is based on timed calibration, not a weighing sensor; it cannot meet a mandatory scale-dose requirement.
Verify variant and installation
The historical row names the MDJ family but does not select standard MDJ, MDJ SPEED or an electrical revision. Confirm the complete model code, rating plate, phase and operating instructions on the offered grinder. Apply throughput, hopper and daily-volume facts only when the maker document matches that exact version. The model search is not proof of stock, current condition or exact ASIN; no current offer is verified.
What else to compare
Before you buy
Does the historical ASIN identify an MDJ?
Its Amazon detail page names the MDJ 75 mm grinder family and part number NS-MDJ-Grinder VS, but does not establish a speed or electrical revision.
What burr geometry and size does Nuova Simonelli list?
The current MDJ page lists flat 75 mm burrs.
What hopper size applies?
The current page and linked brochure list 1.6 kg; a separate USA MDJ OD Digit brochure lists 1.7 kg. Confirm the revision.
What daily output does the maker specify?
The current MDJ page says up to 3 kg/day; a separate USA catalog suggests 5 kg/day for MDJ OD Digit. These are separate maker statements, not measured results.
Are the programmed doses weight-based?
No. The maker describes timed portions. The optional gram calculation derives a value from stored dose settings and grinding time; no weighing sensor is documented.
Is the historical ASIN currently offered?
No exact current Amazon offer is verified.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.
