You can have a lot of fun with these! They can be used indoors or out... string them around a small tree, or along the driveway so they play when relatives come by for the holidays. The sound quality is not great, but the sensor works fine, and you can choose between 1-4 songs, or lights with no music if you get tired of the sound coming on and off. I like them so much that I just ordered them again but with white lights so I can change them up each year. Again, the sound is not great, but you can definitely have fun with them!
