Query: a little noisy but good

I have had good luck with this dust buster. My only complaint is that it is very noisy. You can't use it if anyone else is in the room or if you are expecting a phone call. I guess all of them are loud due to the air flow. It definitely works well and has a very solid feel and adequate batter life between charges. Easy to clean too. All in all it is a good vacuum for small jobs.
