Heats very well and quickly. However unfortunately makes an electronic buzzing/whistling noise when left on standby. The standby mode was good as it displayed current room temp as well, however can't use this feature as the noise is too annoying. Also means I can't just switch the heater on with the remote, instead have to get up and turn on and off at the switch every time. I've already returned it for an exchange, however the new one makes the exact same noise so just seems to be an inbuilt issue with this heater.

I bought this for a caravan and the best thing is the remote control. You can heat up the van before getting out of bed! Great purchase.
