Bests & Worsts Reviews from Amazon

Had a SHARK which lasted almost three years before the battery gave out. Ordered a new Shark mid May and it wouldn't charge at all so it was returned. Bought this Black and Decker model and I charged it fully this AM and the charge lasted all of five minutes with continuous use. Thought perhaps it was completed charged so I tried again. Waited four hours until blue light stopped blinking and tried again. This time I got ten minutes of intermittent use before it completely died again so it's going back. All these companies need to find a new supplier for their lithium batteries especially since the buyer has no option even to replace it on her/his own. I wonder if Amazon reads any of these reviews or ever tests any of these products themselves. So batting zero for two, does anyone have a "go to " manufacturer that hasn't disappointed in the last couple of months?
