I bought this almost two years ago when we first got a dog. I tried to use it, but the dog got agitated because the whole family was inexperienced, and we gave up after only cutting one nail. Since then, we've had the vet trim his nails ( ；∀；) It's practically new, as only one nail was cut. However, it's been stored by an amateur, so it hasn't been maintained, and there's no packaging. But I'd be happy if someone could use it m(_ _)m
