I purchased this specific nail trimmer for my nail shy labordore/Queensland Healer mix because the other, well-known, brand named nail grinders was not doing the job. My "boy" would not allow me to use these other brands on his nails at all. I admit, at first, I ignored his nail growth, up until I had no other alternative except to face up to his challenge as to how I would be able to trim his nails? Since nail trims via the Vet or Groomer cost extra money, and because he would snap to warn me, I resolved the nail trimming challenge would be up to me to remedy. I also did get a muzzle too as he would snap at me, just as to warn me, not harm me, to let me know that he did not agree with my trimming his nails. After searching, finally I saw this trimmer.Why I purchased this trimmer. 1) It's smaller size allows me to better manupliate the trimmer to adjust to better trimming his nails and trims have become much easier with this trimmer other than the other two nail trimmers I previously purchased. 2) Although I still use a flash light to allow the best viewing of his nails as possible, the feature of the attached light is wonderful to help assure you are grinding the proper area of the dog's nail. 3) It is easy to recharge. The charger's cord is added to the same charging plug as my phone and it keeps it's charge very well. 4) the plastic cap that the grinding tool has allows two options to aide in grinding the nails along with the ability to remove the entire cap. This plastic cap has two openings which allows a better focus on the areas of the nail that you would want to grind. 5) It is light weight, easy to handle, not a very loud sound to the motor which has proven to be quite helpful in my quest to trim my dog's nails. 6) Yes, I would recommend this nail grinder highly, and, would buy this again, if need be. This has not only proven to be a handy and helpful tool, I have been successful with the trimming of my skittish dog's fear of nail trims as to where he does not snap at me to warn me, (not bite me), and, he now has begun to trust our nail trimming sessions much better, and seems to show that he has no major issue with the trimmings; he is also showing happiness after the nail trims as I am certain, with his shorter nails, the more comfort he feels whenever he is walking, standing, etc. definately is showing through his positive walking, standing, etc., behaviors.
