Bests & Worsts Reviews from Amazon

This is a market place and my feedback toward the seller is nothing but good things. Everything arrived as it should in the condition it should. I think Amazon should allow us to split the feed backs we give. Because my complaint is against Amazon itself. I would love to give a feed back that says great seller, however Amazon needs to change it's policies. I got this charger for my Kindle Fire HD which I don't understand why it doesn't come with one by default. Until it arrive I was using a USB to wall charger that came with an iPod years ago. When I used this charger I didn't see it charging any faster. I then did some research and found that the iPose charger and this charger put out the same power. I then timed the two chargers and found a 1 minute difference from the same percentage on the battery bar. I then tested against the latest Blackberry charger which is the same thing. The Blackberry charger was faster by 20%. Why by this device? I think Amazon is forcing us to reuse old tech.
