I love this thing so much! I've had it for maybe 3 days now and I cannot believe this little guy's power! I have a pretty big bedroom with a vaulted ceiling in Seattle and when I opened this tiny heater, I thought..."No way will this thing work"...Well shut my mouth! This heats up the room so well, I got up and turned my fan on! It's a tiny bit noisy but I happen to find the white noise soothing. If you need an inexpensive heater, BUY THIS NOW!
