The longevity of the diamond bit depends on how often it's used.

I have had this charging all day and the blue light is still on. I thought the light was suppose to go out when fully charged. Thank you for your help.

So glad I got this!!

Me and my pupper were both always nervous when using trimmers. She has lots of hair, I worry I’m not holding it right, etc. My dog definitely prefers this out of the two devils haha I don’t worry so much about hitting the quick or clippers getting caught. When hair does get in the way, it’s not as impairing either. I just took the guard off as it was too small for my medium sized dog and it works just fine.

Poor quality for large dogs

The quality is probably okay for very small dogs or cats with thin or fine nails. For larger dogs the quality is not there. It is not made for large dogs with thicker nails. It also stops rotating if you push too hard which might be a safety feature but it left me grinding down very lightly for a long period of time for each nail.

Doesn’t Last

It worked okay the first two times I used it. Then the file became smooth so it won’t file and the battery only lasts through maybe one paw. It’s great that there’s no cords but it just doesn’t work. Maybe a small dog with thin nails would work but for my beast with thick nails it was a waste

Dog approved

Glad I bought this nail grinder. Nail clipping is always a chore. My mini schnauzer fights me the whole time and tucks his paws under him. I used other grinders in the past with no luck. This one works great and he allows me to do his nails with out any issues.

battery will no longer holds a charge - have to use it while plugged in

Used several times works great, love this design, relatively quiet. Great with my small dogs they get treats and by now they seem to enjoy the paw massage. Much more easy to handle and quieter than the heavy-duty "shop tool" nail grinders . Easy to monitor progress and avoid reaching the quick. PROBLEM is that after about 6 cycles, the battery will no longer hold a charge. There are many companies with the same design - find one with better electronics - like a charging indicator that works.

Hertzko nail grinder

I love this grinder no cords blocking your way and the sound is so much smoother, less noise and Bella is not so up in arms about it. Nails come off so much smoother and nicer than the previous grinder I bought. Thank u

My 7 lb chihuahua has 5 dew claws, 2 of which wrap around his little paw pads. As such, he needs constant nail trims and the groomers miss the dew claws 50% of the time. It is very stressful for all involved and I have been searching for a long term solution. My pup let me use this to grind down his dew claws with zero fuss. I am still in shock. It worked well, is fairly quiet, has good guards and now I have my long term solution I have been searching for.

Glorified nail file

This only lasted one time. My dogs nails were in need of a trim but the grinder is already weak and no longer filing
