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.

Good. But once switched on, the power supply takes a hit and everything (all lighting fixtures) in the room literally dims.

I thought this would be useful in cold weather but when you set the temperature the fan heats up and then stops. The machine then releases a cold draught, cooling the ambient air. Tried to get our money back but we have had it more than 35 days and Dyson say this is how the machine is designed.

light,easy to adjust .powerful heating

Dyson's brand new Hot + Cool AM09 bladeless fan heater has come at quite the right time. In typical fashion, the British weather can't make it's mind up at the moment, making one day blazing hot, while another could be as cold as ice, and as a result, Dyson thinks it's got your back with its latest...

The Dyson AM09 is the latest 'Hot + Cool' air multiplier fan-turn-heater from the vacuum cleaner specialist. It introduces what Dyson calls Jet Focus, which adds a second airflow aperture ring that pushes air out in a narrower, more precise way.

This machine was sent to me following a two year try with the AM05. The AM05 would work for a bit and then quit. This machine is wonderful and I thank the customer service department for being so kind and understanding and for making sure I had a machine that worked!

Arguably the best small heater fan available, Dyson's newest innovation is powerful and very beautiful – but comes with a hefty price tag

heats a room quickly; powerful small fan; easy to use remote; exact temperature control

expensive; noisy enough to drown out a TV at full blast; can only push warm air around

This smart fan will delight gadget-lovers and hypochondriacs alike

Efficient, quiet fanning, Air purifying is a nice touch, Dyson Link app is great

No Apple HomeKit or Amazon Alexa support, You'll be gasping for air when you see the price
