We have one from Home Depot for about 5 years. It's nice on cool evening or even when bugs are bad here in New Jersey. Easy to use and produces a fair bit of heat.
Plus you can put it in a corner and takes little space on a patio or desk. Minus you only get < 180 degrees of warmth. My neighbor has the round fire pit works well 360 degrees of people around it but less directional heat as it's round
