The Perfect Nail Grinder – HUGE UPGRADE!!!
This is what I am talking about!!! This is the nail grinder that you want. I have the 6 speed original Casfuy. It worked great, but today when I went to use it, it had no charge. I put it away fully charged. So battery wasn’t holding the charge. I began to charge it again, but decided to order a new one just in case. I have two big dogs with bear nails and the old nail grinder could never complete both dogs in one sitting. So I ordered this new more powerful unit with more battery capacity.It arrived Same-Day, 4 hours after I ordered it. Sweet!!! It came FULLY charged ready to go!!! It has a digital display that indicated 100%. I got both dogs done and it had plenty of power to grind the bear claws. When I was done, the digital display says 95% power left. That is what i am talking about!!! It has LED lights and a power wheel with variable power. Nice!!! And it is quiet and has very smooth operation. My 150lb dog doesn’t not like her nails done and this nail grinder is quiet and smooth enough to keep her fighting to a minimal. Grinder feels good in your hands. Absolutely no complaints! In fact, it worked much better than I was expecting. And note that I own the original 6-speed grinder that worked great until issue with rechargeable battery. So in comparison, this new unit is a great upgrade. Well designed nail grinder! And love the same-day delivery by Amazon. And having it fully charged is a huge plus.

Perfect for large dog nails!
I’m really impressed with the Casfuy Smart 6-Speed Dog Nail Grinder. It works perfectly on my large dog’s nails, the motor is strong enough to smooth them down quickly without overheating or struggling. The adjustable speeds are great for control, and the built-in LED lights make it easy to see exactly where I’m grinding. It’s also much quieter than I expected, which keeps my dog calm during grooming.Overall, this grinder is powerful, easy to use, and a big upgrade from traditional nail clippers. Highly recommended for large-breed owners!

It’s a good product—go slow with your dog!
I have been pleasantly surprised with this item. Very easy to use. Seems relatively quiet to me as it’s obviously going to make some noise. I think the value for the money is good. I’ve probably already saved the cost of this item by doing nails at home. I’ve even used it on my own nails so I could get a feel for using it and how to hold it. It’s comfortable to hold, the size seems in line with other nail grinders, the nail guard (which I don’t use) and different speeds help with safety. I’ve used it on my Frenchie, she doesn’t love it but she doesn’t hate it— work up SLOWLY to prevent your dog from developing a bad relationship with nail grinding. Watch videos on how to acclimate your dog.

Excellent nail grinder, and fantastic customer service!
This is a great canine nail grinder! It’s powerful and very quiet. I especially appreciate the different covers. You can attach, it helps. Keep nail dust from going everywhere! I found it for a year. It’s still working great I had a small problem with an accessory, and the customer service was excellent!

My favorite!!! Even my Bichon puppies love them!
Best nail grinder I’ve ever used. Solid, quiet and worth the cost. I raise Bichons and these worked beautifully on small three week old puppies (fast, quiet and easy to use). Didn’t scare them at all. Even the older puppies and adults preferred them to traditional clippers. Oldest seniors were nervous at first. But soon, they relaxed and did well! Will be recommending to my puppy families!

Good product for the price
These work good. I like the light and the different speeds. They are not too loud.

Really easy to use, very powerful!
This is a great nail grinder! I’ve never used one before, and this one is intuitive in its simplicity. You press the wheel to turn it on, and turn the wheel to adjust for speed. The LED lights are bright enough to shine through the nail, making it backlight the quik and making it easier to use it safely.It’s very quiet, and doesn’t disturb my dog at all.I just adopted my dog, and her nails are obscenely long and thick, so we’re going to be grinding down her nails frequently to get her quik to retract and her nails to be comfortably short for her again. Which is specifically why I opted to get this grinder over all the other ones I’ve seen, because it is easy to use and more powerful than the other ones I was looked at in this price range.I highly recommend it, regardless of what your dog’s nails look like, this grinder makes quick work of trimming them up safely.

Still noisy to pets. Not a solution in my opinion and experience with pets

Would recommend these if like me you have a small dog who hates having his nails cut. My chihuahua will not sit still for clippers but these were a breeze and work so well. I was sceptical at how much they would actually take off as other bigger brands had poor reviews but these are a brilliant alternative to nail clippers and keeping on top of nails will now be much easier for me and pup. The lowest speed was enough for us so I can see it working well for bigger dogs too. Easy to handle, not too big or heavy, surprisingly quiet and they feel good quality.
