Review on TRUSTECH Outdoor Patio Heater - Adjustable 1500W Waterproof Heater With Rapid 3-Second Heating, IP34 Protection, And Tip-Over Safety Feature For Balcony, Backyard, And Garage Use by Kevin Kimbrough

I was skeptical at first, we bought a similar heater about the same size and it was not effective at heating the space. THIS heater may be small, but it can sure pack a punch! It was able to heat our entire basement office. I opened the basement door and felt the heat right away. It was warmer in the basement than it was on the main floor ALL because of this little guy! We are very pleased so far.
