I bought it to recover the contents of Compact Flash cards that have been used with an old Canon Powershot G3. Fast delivery, thank you Amazon. First used: fine, but the depression and withdrawal of the card seems a bit hard, probably because the reader is brand new. Second use: nothing. An examination under the microscope shows that some connector pins protrude from others as if they had been partially torn off by removing the card. -> Bin and farewell!
