Query: Kensington 33117 International Travel Plug Adapter

I was very unhappy with this product. The information on the web site states that this is good for chargers. When I received the product the packaging clearly stated that it is not for use with chargers. That was the only use I had for the adapter. I returned it and the cost of shipping, as I expected, and the cost of the prepaid label were deducted from my refund. I feel that I was penalized for incorrect information posted on the web site. I am usually very satisfied with my purchases from Amazon but this was not the case for this order.
