everybody here seems to be shitting on these brands for being generic no-name brands created by random letter generators. but Aukey and Ravpower were legitimately decent brands that had built up a reputation and had some value behind their brand name.
whether you liked them or not, knocking them off amazon is a serious punishment that will have a real impact in dissuade other brands from committing review fraud. they also have to account for a serious sales volume on amazon. this isn't a meaningless PR gesture, amazon appears to actually be taking this seriously.
