This speaker is awesome and I am very happy after trying a couple of other brands for bluetooth speakers.Weight: It is very light. I bought another waterproof speaker before this one and it weighs twice as much.Waterproof: I did not dunk the speaker under water but I did use it in the shower and it had no problems being splashed. It seems to be waterproof as described.Style: I really like the style, it's very modern and fun to hold and look at. The rubber webbing that makes the case around it looks cool and it also is screwed in very securely with little screws rather than just being halfway molded to the side.Sound Quality: I'm pretty picky about my sound quality. I don't buy super high end audio equipment, but I can't stand cheap sound either. It has to be rich and full sounding and this one really is. And it actually gets loud enough. I use it in the car (because my bluetooth connection in the car is spotty) and I can hear it well with the windows down and the wind coming in. The other speaker I got I had to roll the windows up to hear the speaker even at full volume.Solar: Almost as an added bonus is the solar panel on top. I did not get the speaker only for this reason but I'm finding that I really love having it. I let the battery run down and instead of charging with the cable, I just used the sunlight, and after about 20 minutes in the sun, I was able to keep using the speaker for another whole day!I highly recommend this, it's great.
