### ⭐⭐⭐⭐⭐ First Impression is Best
*by K***N on 13 February 2024*

Superb built quality Compact size Separate charger cable, Aux cable, waist band provided Super loud and clear voice Cons: 1.No bluetooth connectivity 2.No usb slot 3.No sd card slot But I use this product only for teaching, hence these features are not necessarry. I picked this product because of the high capacity batterry. No any similar products provide this much big batterry. I will update the review after one month usage.
