This is by far the best business review I have read so much, well detailed with high quality images of the products and you added a video which is incredible.

The Spekaer in the video above is a JBL charge 5, its an outstanding speaker

Yeah, JBL are known for manufacturing high quality speakers, I also owned one of JBL speaker, JBL charge 4, I think it's the lower version of the one you have.

The battery is what I enjoyed most, it can be used as power bank as well to charge phone..

You have done a great review, I wish you the best in the contest.
