I was so disappointed in this purchase. The volume is so low you can't even hear it over the shower. My iPhone in a cup plays louder than this speaker. Also, it doesn't suction to ANYTHING. Worst groupon purchase I've ever made.
Well, it sounded "okay", not great, not even good... but the charge didn't last very long so I had to keep disconnecting it from the wall and plugging in to charge. I played that game for a while, then a few weeks later it just totally locked up and kept beeping. I threw it in the trash, it continued making that slightly awful noise until the battery finally died - oddly that charge lasted longer than the other ones. It was a bit disturbing actually.
This is the worse product I've ever bought, not just from Groupon, but from anywhere. Cheaply made, not loud enough and most of all, it does not hold a charge anywhere near the mount of time it claims. I only use it in the shower for about 15 minutes at a time and I have to charge it avery 2-3 days. Needless to say, I no longer use it, so its only in there for looks now SMH
Mine may have just been the odd ball in the batch, but this worked for 30 minutes and then refused to work. It now will not even turn on no matter how much I charge it. Very disappointed. I opted for a different waterproof speaker.
