I was pleasantly surprised at how quiet this product is! It charged quickly (I can't speak to how long the charge will last since I haven't had it long enough). It has two speeds both are quite--I expected the high speed setting to increase the sound but it did not. It fits well in my hand and is easy to handle--even when attempting to convince a large, old, grumpy boxer that his nails have in fact reached the point where I have to take action. The sound didn't bother him at all! He still wasn't pleased with me bothering his nails but he tolerated it. It works well--his nails are very long and extremely hard--I have found it difficult to cut them with regular dog nail clippers. This product will help me keep them manageable.
good size for easy handling
some reviews have said that replacement head is difficult to find and I think they are going to have to be replaced on a fairly regular basis if you have a large dog like mine with very hard nails. A small breed wouldn't wear the grinding head down as quickly.
