Casfuy Smart 6-Speed Dog Nail Grinder - 50% More Power Pet Nail Grinder with 2 LED Lights Quiet Rechargeable Electric Dog Nail Trimmers File Toenail Grinder for Large Medium Small Dogs & Cats (Red)

Short review for the scroller: Works on Giant Breed black nails (English Mastiff approved) Long review for the reader: Background, I have a 150lbs English Mastiff that is such a mama's boy that he is only a sweet angel when I groom him but is an absolute devil if anyone else tries to. After being kicked out of the groomer for lack of cooperation I have had to find tools that would work for his big size. With the first nail grinder it was so loud and lacked enough power that it would pull on his nail then get jammed and cause him enough distress that we could only get 1 paw done an hour to give him breaks and cuddles. The second grinder I tried that claimed it was strong enough for thick black nails made a complete dead stop right as I touched his nails. At this point he was scared when he saw either grinder and it was a wrestling match to get him trimmed. This grinder changed everything. It is bigger than the more common household ones but does fit female hand (glove size medium), with the black section being a handhold area. The dial for changing the speed makes it super easy to immediately amp it up for his tough nails. With the screen on the base that automatically changes the power based on the nail so with my boy it varies between 6.3 to 6.5 never getting caught and giving the nail a proper rounded edge. It's not very loud and causes zero distress even going so far as to almost lull him to sleep. What used to be a full day event is now just 20 minutes for all 4 paws. I have been using it for just about a year now and my pup is now excited about getting his nails trimmed.

I LOVE THIS THING!!!! I've had it for a few months now (2-3months) and its great. I've only had to charge it once, and it was at like 95%. We dremel our dogs nails once a week and its fine. It's not as quiet as you'd think but it's not loud either. Our dog isn't scared of the noise so idk. We have a doberman who is HUGE. He's 95lbs and his nails are jet black which is why we dremel instead of clip. This thing is a BEAST for big nails. It NEVER gets stopped up. I can push on the nail a bit while it's going which would usually jam up our last dremel and this one has never gotten stopped up from that at all. The bit is great and this thing grinds the nail down pretty quick which makes the whole thing a better experience for all of us because our dog doesn't like it. The light is great too. I do use the guard because it helps me stay on the nail, but what I did was cut a bigger hole in the guard because my dog's nails are a tad too big for it. Works great. Our nail trimming time went from 30min-1hr (constant breaks and jams with our last dremel thing) to like 10mins max because this thing never gets stuck and is super fast.

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.

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.

This is a great nail trimmer for my german shepherd. Its very easy and safe to use. Its large and very sturdy so it files the nails down quickly and efficiently. My dog has zero issue with me doing her nails now. Its not loud at all. Cleaning it is a breeze. Overall its very pet friendly

Works great! My dog is EXTRA anxious and she didn't "love" it, but she handled it way better than clippers! I love having the lights, especially for her dark nails. And all I had to do was hit the button once to turn the grinder on and once again to shut it off. It was nice not having to keep pressing on a button to keep it going. It's not silent, but it's pretty darn quiet, even when it's grinding. I would recommend holding the nail as well as the foot to keep it from vibrating too much. I tried it out first on my own thumbnail and it felt slightly uncomfortable at times, but never painful.

This thing is awesome. I have 2 Buggs (pug/boston terrier mix) they have a mix of black and semi clear nails. They hate getting there nails cut just like most dogs. They don’t love this but it’s 1000% better than cutting their nails. Completes task quickly and efficiently. Easy to use and not too loud.

Works great! Love the battery life, love the speed and I love how the grinder doesn't wear out easily. I have English Bull Terriers and their nails are tough, no more needing to replace the grinder after each use.

Super ale …. Światło niekoniecznie oświetla trzon pazura. Plus że jest bezprzewodowa i szybka ale obcinam nim pazury chihuahua i charcikom i u charcików trzeba się nasilowac 🙈napewno nie jest dla dużych ras . Maksymalnie średnie

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.

super j'ai un carlin première puissance tout ce passe bien il ne bouge pas l appareil est silencieux et vitesse 1 dejà ca marche très bien je suis ravie....

Krallenpflege ist bei uns leider ein schwieriges Thema. Meine Hündin hat schlechte Erfahrungen mit dem Krallenschneiden beim Tierarzt gemacht und entwickelte anschließend große Angst vor der Krallenschere. Mein altes Schleifgerät mochte sie allerdings auch nicht, da das dauerhaft eingeschaltete Licht sie verunsicherte. Bei diesem Modell gefällt mir deshalb besonders gut, dass sich die LED-Beleuchtung separat ein- und ausschalten lässt. So kann ich das Gerät viel besser an meinen Hund anpassen. Das Schleifgerät liegt angenehm in der Hand, wirkt hochwertig verarbeitet und bietet sechs Geschwindigkeitsstufen, sodass man sich langsam steigern kann. Die Lautstärke ist je nach Stufe natürlich hörbar und auf den höheren Einstellungen deutlich präsenter. Der Motor klingt eher hochfrequent als dumpf. Gerade bei sensiblen oder ängstlichen Hunden würde ich deshalb unbedingt mit der niedrigsten Stufe beginnen und das Training in kleinen Schritten aufbauen. Bei uns hat dieser Aufbau tatsächlich rund zwei Monate gedauert. Fast täglich haben wir etwa fünf Minuten – manchmal auch zweimal fünf Minuten – geübt, bis meine Hündin schließlich die höchste Stufe akzeptiert hat. Heute können wir ihre Vorderpfoten deutlich entspannter schleifen als früher mit der Krallenschere. Die Hinterpfoten mussten wir übrigens komplett separat trainieren – jede Pfote war für sie ein eigener Lernschritt. Ein wichtiger Tipp: Niemals zu lange an einer einzelnen Kralle schleifen. Durch die Reibung entsteht Wärme, die unangenehm werden kann. Ich arbeite deshalb immer nur etwa 2–3 Sekunden pro Kralle und mache lieber mehrere kurze Durchgänge. Das ist für den Hund wesentlich angenehmer. Auch die Akkulaufzeit überzeugt mich absolut. Nach rund zwei Monaten nahezu täglicher Nutzung lag der Akkustand immer noch bei etwa 89 %. Das ist wirklich beeindruckend und erspart häufiges Nachladen. Noch ein Hinweis zu den Ersatzteilen: Entgegen mancher Bewertungen gibt es passende Schleifköpfe für dieses Gerät durchaus bei Amazon zu kaufen. Man sollte nur nicht unbedingt den automatisch vorgeschlagenen Empfehlungen vertrauen, sondern gezielt nach den passenden Ersatzköpfen suchen. Insgesamt bin ich mit dem Krallenschleifer sehr zufrieden. Er ersetzt zwar kein geduldiges Training, macht die Krallenpflege aber deutlich stressfreier. Wer bereit ist, seinem Hund die Zeit zum Gewöhnen zu geben, erhält hier ein hochwertiges und zuverlässiges Gerät, das ich guten Gewissens weiterempfehlen kann.
