Review on Altec Lansing HydraJolt Wireless Bluetooth Speaker - Waterproof, Portable Speakers with Built-In Phone Charger and Lights - Everything-Proof Outdoor Speaker, Shockproof, Snowproof - 16 Hours Playtime (Royal Blue) by Bob Richardson

This little hydraulic push speaker is great! It is lightweight yet very strong and durable. It's the perfect size for kayaking and the built-in carabiner zips closed. This allows me to easily attach the speaker to my kayak so I no longer have to worry about losing it. Even if it falls out or my kayak capsizes there is no need to worry as it is IP67 waterproof. I can confirm this is indeed the case because I forgot to attach it to the kayak and accidentally knocked it out. I was scared but thank god he swims! What a lifesaver! I'm amazed at the high quality sound you get from this compact device. It's crystal clear and the volume is high enough to hear from afar. It has good range and connection with my phone. The lighting function adds something more to the device. There are 11 LED light modes that can be changed according to the music. The battery life is fantastic. We can be on the water all day without worrying about her dying. All of this is really great, but what I like most is that it can be used as an external battery to charge the phone. You have no idea how many times that saved my ass. The worst thing is when I go out kayaking and forget to fully charge my phone first. 😳😬 I am impressed with the durability, design, sound and functionality of this speaker. It is worth buying.
