I really like this speaker! I got this speaker so I can listen to my favorite songs while I'm outside doing my work. It sounds great and is waterproof. We do tend to get a lot of rain in Florida. I can use my phone or my tablet. Any device that is Bluetooth enabled will work. It works 49-65 feet away from my device it is connected to. Has a playback time of 4-8 hours. Works perfectly for me. I got 1 Bluetooth 4.2 stereo speaker, 1 user manual, and 1 micro USB charging cable.
