Input: Great speaker, great price, but after only two months of use, my refurbished unit will no longer take a charge! If this is refurbished why has the battery not been replaced? Waste of $100+ dollars. And only one month past my return window... What will Amazon do for me??

Don't buy refurbished, it's clear they don't replace the battery
