I quite liked this heater. I was using it in a pretty large room that was in the attic of a building so I wasn't expecting it to warm up completely. It did a really good job and I was very toasty. I was a little uncomfortable by the fact that it was filled with oil because of spillage but I just kept it away from nearby objects. I fell asleep and woke up the next morning feeling very warm and toasty. It's a good purchase to make especially if you have a large room you want to heat. I wouldn't advice putting it on carpet through. Performance Very good. Heats up quickly. Ease of Use Controls were easy to use. Durability My cousin has had one for about 5 years and loves it. Design I'm not a fan of the design but it's functional. It looks like a little skinny radiator. Safety The oil causes some concern especially with spillage and cost. That shouldn't stop you from trying this product out though. It's likely you can break even on the purchase very quickly.
