The protective cap allows for gentle and safe operation leaving nails rounded and smooth. Won't crack, splinter or break nails. Filings are retained in the cap so there's no mess.
I found that I took the orange cap off and skipped using it at all. If you're careful you can use it without that. I only try to sand my dos's nails one paw at a time and skip a day. Don't hold the nail on the sandpaper too long or too hard cause it heats up and the dog will freak. And don't try to sand against the nail; just let it rest with the rotating sandpaper underneath and use little strokes. This is also good for your own toenails if you're older and have a hard time trimming them or can't reach them.
the only reason i gave this unit one star is that i couldnt post this unless i gave it one star.That being said I bought one of these trimmers and was totally not impressed.They are very under powered and if and if you want a bang for your buck,buy a dremel
good product but i found that with larger dogs it takes forever to use. i have a apbt (pitbull) an she let me use it on her. the price here is awsome wish i had gotten mine here insted of a superstore. i did find another one that i like more its called gentle paws. its more like what a groomer would use an its much faster an u have more control.
