I accidentally ordered the wrong size adapter, but did not realize it until after it was shipped. I figure oh well it is only $5, write it off. Then I checked into how easy would it be to return it, being I never had to return anything back to Amazon before, I figured this would be a good trial run. But Amazon was having none of that, they told me to keep the part and they will refund my card anyway. Now thats is customer service.. Thanks Amazon for fixing my mistake for me, so easily.
