I went river tubing with this speaker and as I was getting in the river, the current ended up taking the speaker away. As I jumped in the water to try and save it, I looked around for 5 minutes and as all hope was lost, reached my hand down and found it! AND IT WORKED JUST FINE! I was working my way back to my group, fighting the current, and ended up losing it again! I was pretty bummed out for about 20 minutes as I thought surely the speaker was lost and even if it was floating somewhere around us down the river that it wouldn't work. As we caught up to a group ahead of us, they motioned us over to them and, low and behold, they had found my Wonderboom floating in the river and it still worked! Upon further inspection when I got back home, even though the "weather door" for the charger was tightly sealed, there was a bit of moisture by the charging port and the speaker will only turn on for roughly 2 minutes before turning off, but plays loud and clear for those two minutes! I will 100% buy UEs products again, I just wish that they truly lasted 30 minutes in the water. I wish that was covered in the warranty because I love this speaker to death and use it everyday.
