Review on 2020 Edition Gray Bluetooth Speaker Backpack: 20-Watt Speakers & Subwoofer for Parties, Festivals, Beach, School - Works with iPhone & Android! by Alicia Jones

My son saved money for this backpack. He wanted to be able to make music at school, on the way to school and while cycling. Amazing quality speaker. It can get very noisy and if he drives down the street you can definitely hear him coming! The battery also holds a charge for a long time. The only drawback are the zippers. Both zippers were broken. We were able to fix one and not the other. So it is still functional because of the simple zipper, but it can only close the side instead of the top at will. He loves the speaker and the bag so much that he still prefers to use the bag with someone else.
