Unfortunately, the Ryobi 40V HP 600 CFM Cordless Leaf Blower/Mulcher/Vacuum (model number RY404150) is one product from the brand that you should probably avoid — at least according to customers ...

Our "Most Quiet" pick, Ryobi 404100 ... He owns a small herd of leaf blowers, from lightweight portable models to an ear-shattering blower/mulcher that he only breaks out in emergencies.
