I was happy with this product for the first 2 weeks, but then all of a sudden the buttons stopped working.
EDIT: Fortunately, Archeer quickly responded online and ensured me they would send a new speaker. Thank you for the great customer service. I'd like to say the speaker itself has great sound and the solar charging works very well. I'm very happy to receive the same product and would recommend this to anyone. I'm confident in receiving the same speaker as it feels well made and has great sound quality.
