Price and rating as shown on Amazon when we collected them. Both change.

The Casfuy Dog Nail Grinder Quiet is the number two pick in this guide. It is a hand-held trimmer with six grinding speeds quoted at 7,000–12,000 RPM, three grinding ports, two built-in LED lights and a removable plastic sheath that collects nail dust as you work. It sells for £23.99 and carries a 4.4 out of 5 rating from 6,447 ratings, the largest review count of any grinder here. The listing gives its item model number as N65, and it was first available on 24 July 2023.

The price is not the only thing separating it from the cheaper Casfuy models in this guide. The speed band it quotes is the same 7,000–12,000 RPM band they quote, so the extra money does not buy more RPM. What it buys is harder to pin down, because the listing disagrees with itself on power. One bullet says the grinder "can be easily recharged with AC adapter, laptop, or other power source". The specifications field on the same page says "4 AAA batteries required. (included)". Those describe two different power supplies, and the bullet that would settle it stops mid-sentence at "It lasts up ", so no runtime figure appears anywhere on this listing. Everything on this page is taken from the Amazon listing as published, not from any testing we carried out.

What buyers actually say

Quoted from customer reviews on Amazon

Verified purchase

“Brilliant product. My dog doesn't like nail trimming but tolerates this one. I tried so many cutters/grinders but this one is by far the best and most effective gadget. It's quiet, doesn't vibrates too much and grinds the end of the nails very quickly.”

Edina Wermeser
Verified purchase

“Did the job well after all other attempts with other methods of cutting our whippets nails have failed. I am very pleased with the ease of use and even though they were a bit reluctant for me to file their nails to start with, they soon relaxed and enjoyed the process. Easy and safe to use.”

Questions people ask

How many speeds does the Casfuy Dog Nail Grinder Quiet have?

Six, quoted across a 7,000–12,000 RPM band. That is the same band several other Casfuy listings in this guide quote at lower prices, so the speed range is not what the £23.99 buys.

Does it run on batteries or a rechargeable cell?

The listing gives both answers. A bullet says the Casfuy grinder can be recharged with an AC adapter, a laptop or another power source. The specifications field says 4 AAA batteries are required and included. The page never states which supply the grinder actually uses.

How long does it run on a charge?

No figure is given. The only sentence about runtime on the Casfuy listing is cut off mid-sentence at "It lasts up ", so the listing does not say how long it runs.

How loud is it?

The listing title states 45 dB, and the product description calls it low vibration, gentle and quiet. We have not measured the noise ourselves.

What do the three grinding ports do?

Casfuy lists a small port for small pets, a medium one for medium-sized dogs, and an unprotected grinding head that the listing says works best with larger dogs' nails.

What comes in the package?

The listing describes two LED lights, three grinding ports, a removable plastic sheath, and 4 AAA batteries listed as required and included. The package is given as 20.4 x 10.3 x 4.7 cm and 310 g.
