Fast and perfect medium manufacturer.

I use this card between my PC and my Macbook Retina to quickly transport large data masses. The transfer speed is greater than any key UBS, CD or external hard drive that is in my possession.
For example, it is possible to play 1080p video without lag tens of gigas without waiting for the player (VLC) resume playback.

After a few months of use, I noticed a small crack on the corner of the board, most likely because of a shock when the card exceeded my Macbook. I sent a picture to Lexar (who answers me in French, a good point) which, without having had need to insist, offers me a gesture of goodwill and to replace me for free.

This is my second card Lexar 128Gb (the first was a 133x speed) and the quality of their products and after-sales service, have convinced me of their seriousness. I probably will not buy competing cards if I had the opportunity and advise all my friends that mark.
