Review on Ultimate Outdoor Entertainment: Portable Swimming Pool Float Bluetooth Speaker - Waterproof, Shockproof, and Dustproof with Superior Sound Quality by Albert Lee

I wasn't expecting too much from this product but I saw the test video for this speaker and decided to give it a try. It has a clear sound, the battery lasted at least 5 hours after charging. I did notice that when you turn up the volume with the real speaker it gets a bit distorted, but when you turn up the volume with the phone it sounds perfect and it actually gets a lot louder when you use the phone volume. So I always check if the sound is set correctly before I go to the pool. I didn't care. It floats great and after someone fired the cannon it flipped over and the audio got a little distorted but I just shook it to get rid of the excess water and it worked great! This is a good choice for an affordable pool speaker.
