Originally, I wrote a negative review of this speaker due to the distorted audio and low volume I got at first. But, after a little more than a week, it seems to work better (as of now). It really does make handheld scanners a LOT louder than what you would get from the built-in speaker. I suspect that there's something wrong with the battery since I seem to be the only one with this issue. I will keep using it for another week or so, and if it acts up again, I'll may have to get a replacement.
