I love these lights. We put them on our Christmas tree (3 strings to lightly cover a 7 foot tree that has a lot of space between branches). Regular Christmas tree mini lights are too bright for my liking. These micro drop lights add a delicate touch to the tree: like little stars peeking through the night sky. Also my batteries last for a long time with these lights. By using batteries instead of plug in lights, there is no emf radiation (important for a place where children like to spend a lot of time playing). I love the amber color. It is similar to candle light. Much nicer than white led lighting. Two of the three original sets I purchased didn't work so I emailed christmaslightsource and 2 new strands (pre-tested) went out in the mail that same day. Great customer service. Thank you.
