I'm a professional musician, so I can be a bit harsh here. My wife bought this to use for toast etc at the wedding. It was a breeze to set up and find on Bluetooth. It had decent sound for a spoken word, but feedback was generally too weak. Obviously, this isn't a high-end wireless microphone, nor does it claim to be one. The mic worked perfectly for its intended purpose but was not up to par for a high-end commercial stage mic. As this was a one-off, I cannot criticize the battery longevity or the performance of the device over time.
