We received these as a Showplace item for our Airbnb.  They are fabulous...We have a large covered patio with lots of seating options for our guests.  And our home is somewhat in the country close to a Lake.  As you know, Mosquitos in Texas are the size of birds (haha) so with the flip of a switch, our guests are now protected.  Everyone is using them when they are there.  We liked them so much that we purchased a string for our own Home Patio.
