Freestanding patio heater

Bought this on sale. My thoughts were maybe it will last one season. It surprised me. The heater is well built and easy to assemble. It exceeded my expectations. I did modify one thing. I added a wooden table top to the existing top. This extended the amount of space. Because this thing is huge. Highly recommend.

Great purchase

Purchased this for my mom to be able to sit on the the front porch during cooler weather months and stay warm. Putting it together only took about 30 minutes. Only hard part was removing the screws from the packaging. You will need to buy 22lbs of sand to weigh it down if you live in high wind areas. Other than that it works great and keeps the area really warm and toasty
