Reliable for humidifiers

This was my third purchase from Duux, I got the Beam Mini this time after owning a full-size Beam for a couple years. They're consistently good machines. The Mini works well for my home office; it's quiet like the bigger one. Delivery took 6 days to reach me in Scotland, which is standard for them. I always come back because their stuff just works and lasts.

Good fan, quick delivery

I ordered the Whisper Flex Smart Fan a few weeks ago. It got to me in Manchester in about 4 days, which was faster than I expected. The fan itself is pretty quiet even on higher settings, good for the bedroom. The app connection was straightforward. Overall happy with this purchase.

Quick question on delivery, how long does it usually take for stuff to arrive? Living in Manchester, need a new humidifier before my plants shrivel up.

I ordered a fan a few months back to London and it arrived in like 3-4 days. Pretty standard, nothing crazy fast but not super slow either.

Mine took about 5 days to get to Glasgow. They're usually pretty good though, you can track it once it ships I think.

Hey thinking about getting that Whisper Flex fan, but are they actually super quiet? My old one kept me up at night.

C Colin 4 months ago
Yeah, they're pretty good. I have one in my bedroom and it's definitely quiet enough for sleeping, especially on the lower settings. You barely notice it.

I guess it depends what you consider 'super quiet'. It's not silent, obviously, but compared to other fans I've had, it's really low hum. Worth it for sure, great airflow.
