Bests & Worsts Reviews from Amazon

I was really excited about this speaker after reading the reviews, but it stopped working after three weeks. There are other reviews that mention this. Unfortunately I missed the return period so now I am stuck with a speaker that won't turn on. And yes I know how to charge it. I hope the manufacturer reads this and wil exchange my speaker. I bought their backup battery at the same time, so I know they have good products. Unfortunately this must be a defective speaker with the power button. UPDATED 11/4/17 - I was immediately contacted by customer service at Anker after my review and they asked for my serial number of the defective speaker. They sent another one out free of charge. I was very impressed with their high level of customer service. So far the new speaker is turning on and I hope it keeps working.
