Review: If You Need a Great Bluetooth Speaker, You Found It! - This is an amazing portable speaker. I purchased a larger one earlier this month and it worked well. So, I decided to purchase this smaller one for the patio, dining room and garage. Sound clarity is awesome, easy to link to your devices and a great price. Battery life is true to form and it fits in so many places with ease.
Review: Faulty and missing items - 1. Missing power cable 2. The logo seems to be scrap off like it's being used before (see photo) 3. Sound is distorted, seems like it was used and condition is bad
