Unless you're the most devoted Dyson loyalist, you'll find much better values if you shop around -- including Dyson's own AM05.
The Dyson AM09 Hot+Cool performed very well in our tests; and offers a distinctive; functional; feature-rich design.
Though very solid, the AM09 doesn't outperform much cheaper competitors by a wide enough margin to justify the price difference; If you misplace the remote, you'll be unable to access common controls like oscillation and the sleep timer.
