Casifor 2 Pack Dog Nail Grinder Replacement Wheels - Painless & Safe Diamond Tip Filing Heads for Pet Nail Trimmer - Perfect for Small & Medium Dogs Grooming at Home

Only product both of my dogs are comfortable with letting me do their nails.These work, and are fairly easy to change out. They do seem to have a very thin abrasive layer, which wears off quickly. Also, the actual tool does not let you use other areas of the surface when using the protective housing, which causes a quick wear line -- leaving the rest of the surface unused.Not very much value here, but most of these replacement heads seem to be custom fit to the actual tool, which makes it difficult to get a good pet nail trimmer.The product is good, it does what its meant for but it's not for large dogs. I have a 60 pound dog that is scared of nail trimming so I thought this would be good which it is because he isn't scared of it. However it's not meant for big dogs because I can barely file one or two nails (which are slightly long) before it gets somewhat smooth and doesn't want want to file properly any more so back to trimming nails.These were exactly what I needed for my pet's nail grinder.I have bought many grinders !! This is the best I have purchased. Thank you.They work great but after just the first use I can see where they have worn down quite a bit. I do not expect them to last long.As expectedI've been using this for the past 4 years on my 165 pound Rottweiler with NO TROUBLES AT ALL !!! I don't know or understand why there are people on here complaining that this, "Doesn't work and isn't powerful enough" to work on their "large" 60 pound dog.... My dog weighs 165 pounds (not fat) and has Very Thick black nails and I've had zero trouble taking up to 1/4" off all 16 toe nails, running at Full Power from start to finish with battery power left over. They key to trimming a dog's nails with this is to not try to "grind down" each nail in its entirety at one shot, especially if they're a bit long. Because the effect the grinding wheel has on the nail is that it generates heat, to which your dog can feel easily because there's a VERY SENSITIVE part inside each nail called the "Quick." It's full of nerves and blood vessels that are responsible for nail growth. It's the part that bleeds easily if you unfortunately cut the nail too close. What I do is start on my first nail, get to about 1/2 off what I plan to do, then move on to another toe nail while that ones cools down and keep going from nail to nail until and then start back on the first. But as you get closer to the Quick, you shouldn't spend as much time on each nail because your dog will be able to feel any heat easier. And as for the life of the grinding wheel, I've been using the same one foe the past 4 years on a 165 pound dog with very thick nails and it still works fine!This product was used to cut my dog nails, for the first time. I am a complete baby.Kam super schnell an. Und die Beschreibung ist auch Top, obwohl es besser wäre wenn es auf deutsch ist.Produkt hat gehalten was die Werbung versprochen hatDie Ersatzteile sind einfach zu wechseln und funktionieren perfekt.Ein Glücksfall, dass der Vorgänger kaputt ging. Dieses ist sehr viel besser, effektiver, schneller und auch noch leiser. Bin sehr zufrieden.
