This wireless speaker is awesome! My friends and I went on a really long and tiring hike once and decided that we needed some pumping music to push us to finish. We pulled the speaker out, connected it through bluetooth, and jammed to Beyoncé! The connection would go out once in a while, but that was only due to the fact that my friend (the one controlling the music) and I were walking at different paces and so we gained distance between us. Overall great product and really inexpensive for the quality you're getting.
