Great speaker for the price
I tested this speaker with my One Plus smartphone and Macbook pro laptop via bluetooth and AUX cable for about a week. The speaker also has a small embedded mic. I also used it for voice calling and it worked perfectly without any issues. I would give it 4.5/5. Its pretty loud for its size and connects flawlessly with light indicators. I got 6 working hrs for a full charge.
Its not the best and loud sound quality. Its definitely louder than smartphones, laptops and computers so I can compare the sound quality to computer speakers
1. Cheap ($15 when I bought it)

1. Could not connect two devices as advertised
2. Not the best sound quality.
