I've owned four strands of these for a couple months now and have found multiple uses for them. First of all, they are just so fun and respond really well to music (and even your voice). They have a battery pack, so you can put them anywhere (like a Halloween costume!), around your desk at work, a locker. They are the tiniest little bulbs on a thin and flexible wire, but so bright and pretty. We have taped them into our front windows for the holidays (super light so scotch tape will easily hold them up) and you can see them from far away down the street. We also used them during a power outage, just wrapped them around the banister so we could see to get up and down the stairs. Note: You have to HOLD DOWN the button for a couple seconds to turn them on AND off. They also have an auto shut off which is super handy. The batteries last a really long time, we have been using them for awhile and have not had to change them yet. They also do not get hot, or really even warm, so the possibilities are endless. The price is also awesome. I'm buying more, we want to put them in all the windows now!
