The delonghi panel heaters is super simple and easy to use, and we love the slim design as it does not take up much space. The timer feature is great so that we can do not have to worry about it running all day or night. The only negative is the feet that were included, when they are screwed on the heater does wobble and I fear this may be a safety issue if it does fall over as it does not have a safety feature to turn off if it does fall over.
