As I look at reviews at Back Country and other retailers I notice that there are a lot of negative reviews for the HyperFlow, but generaly positive reviews for the AutoFlow Gravity Filter. They both have the same underlying filtering technology, they both require back flushing, yet the reviews are very different. Does this indicate a fundamental problem with the AutoFlow?
