Query: Excellent product!

This is the second space heater that we have purchased. The first space heater takes forever to warm up, the DeLonghi TRD0715TSafe Heat Oil-Filled Radiator heats up a large bathroom quickly and so much heat flows out that the heat is felt in the bedroom.We are very pleased with the product. I definitely recommend it.
