The Patio heaters have worked very well for us at our restaurant. They are fairly lightweight so easy to move.  I would give 5 stars except for 2 things: the wheels dont seem very sturdy. This is fine if you won't move it much but for a restaurant where we need to move them every night it may be a problem down the road. The only other caveat is that we havent had them for long, so relatedly, we dont have any experience on that score. So far though, they have been working great for us
