I expect a smoother mechanical for a super expensive appliance.
This is the second unit i have exchanged. Disturbing noise got better but still persist.
It maybe a common issue with this model.
Not sure how it passed the test.

Really satisfied with the dyson, it looks and works real good. The heating of a small room is pretty quick and the fan speed is good too. The dyson link app is fantastic.

Worked well for about a month, then just refused to work again. I know it’s under warranty but seriously why do we have to pay almost a thousand dollars to have to chase our tails to get satisfaction. I will never buy another Dyson product. This one will be in the appliance graveyard.

This is a Dyson product so it is beautifully designed and very well made. In terms of its heating capability, this is an area of weakness. It is important to know that it is not possible to increase the heat output of the machine. It has one heat output setting. Increasing the temperature setting does not increase the heat output of the machine. Otherwise, it has great features. The digital display on the machine is interesting (but more of a gimmick) and I don't use it much. The smartphone app is excellent. One feature - the ability to control the oscillation function and even the exact direction of airflow, is excellent.

My husband was so excited that he even bought 2 units and went back to the shop for the 3rd just after a month from his first purchase. Indeed it works really well in our home.
