Norwich GB
Works! I have it on in the bedroom at night and find I don't wake up feeling dry eyed.
Bit fiddly to clean and small tank so has to run on half speed to run all through the night.

Sunderland GB
This item was bought for someone with mild respiratory problems exacerbated slightly by heating radiators. For this it works quite well on a the low setting, it just adds a little moisture to the air making the heating a littlle less harsh & litle easier to breath. Used sparingly no condensation or damp problems.
It's a bit of a pain to clean, not so much the daily clean but definitely the weekly clean.

The 2 different settings are great. Automatically turns off when run out of water. The low setting is more than enough for me.
The light is very bright. Wish it had a detachable plug at the back, have to keep unplugging it from the wall each day to empty. Couldn’t put it in original place due to having to unplug it all the time. It is quiet big but not huge. It is rather noisy but I’m used to it now and don’t even here it.
