Really nice unit, especially for the price paid.  If you hook this up directly to a propane line, as I will be doing, I would recommend that you add substantial weights to the bottom of the fixture (were the propane tank would have been) to give it stability.  It is fairly 'top-heavy' and could easily fall or blow over.  This is both a safety risk and could damage the heater.  I will be very happy with this purchase and Wayfair makes it easy for me to buy these types of items for our remote properties.
