I am extremely impressed with this Lasko Portable Cyclonic Ceramic Heater. We moved in to our home 4 years ago, in the late fall. We were having some issues with our furnace and we weren't sure how hard it would be to fix. We went out and purchased two of these heaters from Lasko to help heat the space until we could get the furnace issue worked out. I was immediately impressed. These little machines take up very little space, put out a good amount of heat and are programmable to either come on and heat the room to a certain temperature or to run for a specific amount of time before shutting off. We put a heater in each of our children's rooms. I felt comfortable having these in their rooms and I wouldn't ordinarily feel safe with a space heater in a child's room. These, however, were not hot to the touch, didn't require additional clearance around the unit to be safe (though we did provide it) and shut off if knocked over. When we were using these primarily for heat, we set them to a specific temperature and let them run as needed. Now that our furnace is no longer a problem, we use these to warm up the kids' rooms before they go to bed. We set them to run for 1 to 3 hours depending on how cold it is outside and they shut off after that. I like knowing we aren't wasting electricity by having them run all night and the kids like getting into bed in a room that is a little warmer than we like to keep the bedrooms for sleeping. After having our units for a year one of them stopped working. My husband contacted Lasko. They asked that we snip the cord off of the unit and mail it to them along with the model name and number of our unit. We received a replacement via UPS within a week. Their customer service was outstanding!
