Good sound for a little speaker, most would sounded scratchy when loud. But this one didn't and light weight easy to carry.
But delivery was terrible, too way to Long for deliver. And seller never contacted me or sent notification it was on it's way. Or updated delivery status, which was locked in as processing... Nothing else
Description didn't say it only plays MP3 files, no instructions on how to tune FM radio or set it's presets, just keeps advancing to the next preset that the factory must have set. Sound volume is excellent. It's worth the price though.
The QFX 8 Bluetooth speaker was smaller than shown on the Groupon advertisement, I had expected it to be the same one as shown by Groupon. I received my QFX 8 in a timely manner and so far I am happy with its performance. I just wish that next time I received exactly what your advertising in terms of dimensions and size.
