It's not as quiet as other smaller ''dremels'' we can find on amazon and it vibrates way more, that being said it is WAY better. I've had a cheaper one for years. Very quiet, no vibrations. Took me ages to do my girls' nails (especially the older one, she has very strong and thick nails). This one is a game changer honestly. My back is very grateful for this dremel.
Absolutely worth the money as it will save you lots of time and frankly, even if it is noisier/vibrates more, in my experience my dogs prefer this one to the smaller ones that would take an eternity to get the job done. It's not as stressful for them if it lasts 2 minutes VS 20 minutes.
