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

Seventh in this guide, the Dog Nail Grinder Electric & Cordless operation is a purple, two-speed hand-held tool with a diamond grinding head, two LED lights and three changeable port sizes so the same unit can be used on dogs, puppies and cats. It costs £20.97 and carries 4.4 out of 5 from 3,508 ratings, and the listing has been up since 13 April 2023.

The runtime claim is where this one separates itself from the Casfuy models ranked above it. It quotes 5-6 hours running per charge from a USB cable — sitting between the 7 hours claimed by the £24.99 and £23.99 models and the 2 hours claimed by the £21.24 one, so the same rough price buys three different promises. What it does not quote is any RPM or wattage figure at all, which means the 7,000-12,000 RPM band running through the rest of this guide stops here. Two other numbers in the spec table are worth flagging too: the item weight is listed as 400 g, against 176 g and 240 g for the two listings carrying the same LGL007 model number elsewhere in the guide, and the listing says batteries are required but not included while also describing the tool as rechargeable. Everything on this page comes from the Amazon listing, not from testing we carried out ourselves.

The listing gives 400 g as the item weight, with dimensions of 16.8 x 3.8 x 3.4 cm. Two other listings in this guide, both carrying the model number LGL007, give 176 g and 240 g.
