Anyone who is looking for a fast micro SDHC/XC card should look at the Lexar 633x series as it is one of the best options on the market. The performance in our tests was really good considering it is "only" a micro SD card.

High performance; Backward compatible with slower readers; Available up to 128GB; Added USB 3.0 reader; Flawless work on various devices

There are really no cons worth to mention but price could be always lower

Have several of these in 32 and 16 GB sizes and they're awesome. Haven't had any of them fail yet and they are FAST! I used one to replace a class 10 card in my phone and saw a huge boost in performance with the apps that I had installed on it.

I have 2 of these Micro SD cards now, one for over a year, and then I bought another one recently. Very high quality and I have never had a problem with them. Would recommend to anyone who needs a good quality micro SD card for filming video or shooting photos.

I bought this SD for a price first - in my country same card costs 3Xof this price. But I can compare it with the original Samsung card of the analogous parameters - I did not feel any tangible difference. So sincerely recommend it without hesitation - worse every cent of its price.
