+ Did come with two units (IDK why that other customer said she only got one light unit)
+ Decently bright
+ Mode switch on bottom of solar receiver allows selection of static white lights or flashing.
+ Nice quality thick gage wire relative to another set I bought at the same time
+ Fast shipping
- Electronic components seem poor quality. I do not expect these to survive beyond one season, even with being stored for winter.  This is the only reason for the 4 stars.
