Review on The Ultimate American Flag Cooler with Bluetooth Speakers (20-Watt) - Perfect for Parties, Festivals, Boat, and Beach! Rechargeable Speaker Cooler, Compatible with iPhone & Android (2020 Edition) by Roberta Berg

I received this today and had it charged for 6 hours. None of the lights came on. It only works when connected to the network and is literally no louder than my phone. We'll be back tomorrow. Update: The seller provided a promo code to get another half price item. The backpack I got instead of the cool box is made of a different material. It gets wet and dirty easily, but it was fully charged and worked fine. I haven't had any issues with it so far and it comes with everything I need plus a few extras. I don't think it's great to take to the river for its material, but it will do the job.
