Bests & Worsts Reviews from Amazon

I purchased the edenpure 1000 and found that the main difference between it and other space heaters is price. I own several other space heaters including one 1500 watt unit with a fan and one 1500 watt oil filled radiator style heater. I can't tell any real difference in the heating ability of any of them except one thing...price. I purchased an oil filled radiant heater from Target for $28 which seems to do just as well as the edenpure which cost hundreds of dollars more. Not a good value.
