Purchased this recently and it works exactly as promised. Easy to assemble, directions are clear, start up, operation and adjustment are very simple. All in all it would appear to be a great product. Five stars if the weight in the bottom were more substantial (you will likely want to lay it down in winds above 30 mph) and the hood were a single piece rather than an assembly of multiple pieces....still not bad though. 21 degrees last night and my patio was still kept nice and warm.
