Very happy to be giving a lot of 5 star reviews lately, but that's good luck with shopping. it's how it should be. This heater is great, you only need a low setting for an average bedroom. some light clicking when it's warming up, maybe a few minutes of it and not repetedly. but that's basic physics at work on the metal. your car engine also does this when it cools off. I have not one complaint about this heater, it does exactly what it should, and the controls work fine for me.

As with all Delonghi products, this heater is quality constructed, safe, easy to use, provides heat as advertised and appears if adjusted according to the desired temp of the ambient air will perform very well as a safe space heater.

I love this heater. It takes a little while for the room to heat up, but if you follow the instructions it is a great product. It keeps a room toasty warm and the heat can be adjusted. I brought one for my mother and my friend, and they love it, too.

Definately did the job I needed it to. I live right next to the beach in a 1500 square ft two story condo. So during the winter time it could get chilly due to the dampness in the air and the lack on insulation the building has. If we run the heater is bakes the upstairs and its still cold and drafty down stairs. So this unit does a great job just cutting out the draft and keeps it a confortable temperature. It sure is really quiet too. The heater is so noisy and this unit saves us from having to turn it on.
