It's delivered on all fronts! Heats up very quickly whether it's in an open plan room or a small ensuite. Temperature regulated really easily and the Eco function adds another layer. My one small issue, hence why I didn't give 5 stars is there's no timer clock to set! I can set it to turn off but not to turn on at a prerequired time - will have to buy a timer plug. Definitely will be buying another one.
