Used these to decorate an apartment overseas for last Christmas. What joy! They're lightweight, they do not intrude on the room, each strand is quite long. I bought a local USB block and voila they were a real hit. Sadly, they do not connect inline but that's not too bad. If you were to decorate a tree with these, you might want one continuous strand, but for the price point, they're really great and add a warm glow to the room for late night, midwinter, movie watching. Safer than candles and almost as romantic.
