I really have enjoyed the lighting as wells the heat the unit puts out.  We have had the opportunity to use it in the months of March but due to windy conditions in April not a lot of use.  so when I recently went use it I noticed an abnormal amount of rust on the upper level hammered are of the structure.  I am concerned the rust will propagate and deteriorate the sub assembly on the top of the unit.  I called Wayfair this afternoon and let them know of the condition and also make the community aware of the conditions.
