Bests & Worsts Reviews from Amazon

Aug 30, 2017 UPDATE TO THE UPDATE: Imagine my surprise today when I opened the door & found on my porch another unit sent to me by Baccus Global! I hope this one works well. I am charging and will post another update in hopes that it will help someone else in their purchasing decisions. This is a different looking unit, but basically like the other ones. Service was better than I had thought, and now I hope this unit is better than the other two!!! I purchased this unit in Sept 2016 from Amazon. I charged it per the enclosed instructions. After using the unit one time for my husband's CPAP machine during a power outage, it would not recharge. There is no option to return it to Amazon even though there is a one year warranty on this unit. I called the manufacturer, and they want me to pay to ship it back to them to be repaired. I am thinking with the weight of this unit, it would cost a good bit to ship it. If it does the same thing again, after one usage, I would be throwing my good money after the bad. I am weighing my options. Has anyone else dealt with this issue on this product with the manufacturer or Amazon? August 29, 2017 Update:Ok here's the update. I spent the $46.00 for shipping back the bad product, got another one on July 29th- won't hold a charge for more than 2 days. So I called them back after trying the charging process a 2nd time, did the same thing. I was told I'd get a call back for a return shipping label since the product was bad (again) when I got it. Then nothing, so I called again on Aug 25th, was told the same thing. Still no call back and no return label. My warranty will expire on Sept 2nd. so I guess they are waiting me out.
