After exchanging emails and video I have changed my review to 4 stars. I was advised the unit may settle overtime and become quieter. I was also offered a part refund. I do appreciate the time, effort and communication to from comfee to help solve the situation. The unit does cool the room down and quickly. So I will still use it this year, however just not for very long given the noise.

Well, I did get a portable ac unit for a good price, well I thought was.
It does work to cool the room down and quickly. It definitely does that.
However.... it is very load. The actual fan isnt that bad. Its the vibration and drone from the case I think. You can hear it from downstairs. We still use it but only before bed to cool the room down. Im pretty sure its annoying the neighbours.
I bought a vibration mat to help, but it was of only little use.
Now I thought this price was to good to be true because I bought a unit of amazon that was cheaper still. It was a lower btu rating. This unit was for a relative, and I can say that it is way quieter than my unit. Yes it doesn't have some bells and whistles like the unit I bought. But my relatives unit cools the room down well, all be it not as quickly.
Its a shame really. We have ended up putting weights on top of the unit to try and stop the noise. It helps somewhat.
We might have just got a naff unit, im not sure. For the odd occasion we will use it.
Next day delivery was great though
