Out of the box I do have to say the instructions are horrible. Someone that doesn’t have the experience putting things together may have a difficult time. Once together, did like how you can adjust the height and base width. In using it outside, the first time, the heating element did heat up quick.  The heat was felt out 4 feet from the unit when it was positioned at 5 ft height.  Will try again at varied heights but I unfortunately don’t see it heating my entire 12x12 patio. May end up using it in the garage gym.
