Its essentially a large quietly vibrating nail file

The only down fall and maybe it was a packaging mistake was that it didnt come with directions

Dog tolerated her nails being filed

I tried to use it instead of the clippers nails were just too thick

More like a mellow hum

Product came with absolutely no directions not even something directing me to a website that had instructions

It took a really long time to make any progress on one nail but it did work

However for this to be effective on large dogs you really need to use it weekly otherwise it would take entirely too long
