Review: Awesome - I love it ! Easy to use , volume was pretty loud , overall great quality
Review: Good portable amplifier - Works quite well. I ordered to use at an outdoor yoga class and it did just what I needed. If needing to cover a larger area or group outside, might need something with a bigger speaker but for small groups outside or larger areas inside, it's really good. Shoulder strap is really handy.

### ⭐⭐⭐⭐ Great product for an affordable price
*by D***K on April 27, 2022*

I love this sound system overall, but my only problem is that my package was delivered, yet it went to the wrong address in my apartment building. On the day my package was delivered, it was for another apartment building nearby. I thought that the delivery man swapped my package for the address on the package I was given, but I was mistaken. When I went to return the package to the right address, my package was not there either. Fast forward a few days later, one of the residents of the building knocked on my door. She said that my package was delivered to her address by mistake, but at least I finally got my package. It was probably a mix up when the delivery man was making rounds to deliver mail, but stuff happens. The product was not damaged when I received it, and taking it out of the box. The sound was clear, and loud enough to be heard from a 50 mile radius, overall I'm satisfied with the product. But the delivery part of my package I'm not satisfied with, it could've been better. I'm just happy I finally got my package.
