What you are getting

Ten diamond-coated replacement heads for $9.98 — a dollar a head, in a quick-change fit.

Its twin on this shelf

nqnqvl publishes the same five bullets, word for word. Only the count changes: “Quick-Change 10-Pack Design” here, “Quick-Change 20-Pack Design” there. The references run in sequence — H2-HAZ0064-10 here, H4-HAZ0064-20 there — and the barcodes share their first eight digits: 0766717973944 and 0766717975955.

Two brand names, one catalog. The comparison that matters between them is not quality, which neither documents, but the count: ten heads at a dollar against twenty at 74 cents.

Where a dollar a head sits

  • nqnqvl, 20 heads, $14.88 — 74 cents
  • hiSpkNix, 10 heads, $9.98 — $1.00
  • LUCKY TAIL, 3 heads, $23.99 — $8.00
  • LUCKY TAIL, 2 heads, $19.95 — $9.98

The one measurement that is missing

No head diameter is published, and no grit. Diameter decides whether a head seats in a given grinder; grit decides what it is for. This listing carries neither, and “Compatible with most pet nail trimmers” names no machine.

What it does publish

A diamond emery surface, a larger grinding edge than the maker’s previous version, and a quick-change fit. It also claims “Low-Decibel Operation” — which belongs to the grinder, not to the head screwed into it.

The questions owners ask

Why is this a dollar a head when the twenty-pack is 74 cents?

Because the pack is half the size and the price is not half. $9.98 for ten against $14.88 for twenty. Nothing in either page documents a difference in the head itself — the five bullets are identical, the references run in sequence and the barcodes share eight digits. On the published evidence the per-head price is the whole comparison.

Does "low-decibel operation" mean these heads are quieter?

No. The bullet reads "Quiet motor compatibility minimizes noise" — the motor is in the grinder, not in the replacement head. A head cannot make a grinder quieter; it is an abrasive drum pushed onto a shaft. The claim describes the tool these heads go into, and belongs on that page rather than this one.

What grit are they?

Not published. The listing says "premium diamond emery material" and "upgraded sharpness", neither of which is a grit number. Only LuckyTail names grades on this shelf, and it names them in words — hard and soft — rather than numbers, so even those cannot be compared across makers.
