They delivered my old version of CF(Orange One).I called Customer service, do you know what they said?"We are temporarily out of stock, so we sent you upgrade one(better one)"Do they think we are ***.As you know Orange one says 135X and blue one one says 80X.But blue one(brand new one) is faster and more expensive.I compared two CF with my RebelXT, there was slight difference in writing speed in Full Burst with Raw.I hate this oneline transaction.
