I'm pleasantly surprised at the heft and build quality of this speaker. I've only had it a little while so far, but my wife and I were having dinner in our outdoor courtyard and the sound carried extremely well.
The weight and heft ensured much cleaner bass than most of the bluetooth speakers I've owned and I liked the rope loop, as I can attach it to a caribiner.
No chance yet to test it getting wet, but I'll probably go for a swim tonight and I have a good feeling that this speaker will do just fine!
