Bought this as my jack russel hates having his nails done at the vets. Hes an old boy now and really grumpy, he doesnt walk far now and they grow long rather quickly, i used these for a few minutes every day for the first week, then every other day and now once every few days and it keeps nails to a comfortable length for him without putting him under any unneeded distress.
It is reasonably quiet and well built not cheap or flimsy like some I've seen. My boy soon got used to it and now comes and lays relaxed while his nails are being done.
Would highly recommend this product.
