After looking at the many good reviews of this costly heater I decided to buy one, when I received it I was a little confused at the on and off switch ? which is a little tiny pin like switch no bigger than a match head.. this i found to be ridiculous !! The other Delonghi Dragon 4 heaters i looked at on line where different, having a proper easy to see and much larger on/off switch plus a more user friendly operating panel. I bought the wrong one, not happy with it, maybe it's an older model ? Hope this review helps
