Good patio space heater

Overall, great value for the money. The heat is 4/5 stars; not quite as much heat as I was hoping for in the dead of winter, but, it gets the job done for sure. The assembly was 4/5 stars as the blue film was quite challenging and time consuming to remove during assembly. Everything else is great: looks great, functions great, good value for the money. May purchase another.

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.
