I bought a class 10 Samsung and returned it after I found out the speed was actually lower than that class. After buying and using many different brands, I have found that this company makes the fastest, highest quality, memory cards. Other companies advertise their cards as being certain classes but they are not up to par. I think $19.99 is a steal; best buy sells this product for $39.99. (As of 7-11-12)The card I recieved must have been a dud. It is broken and my phones are not able to read it. When I try to use it in the computer it says the card is damaged. I will be returning to Amazon.
