Top notch !!! Bought when purchasing my Canon sx530 I do not know if it's coincidence or not but Amazon quite a flash sale for 15 minutes at a price of 29.90 euros !!! Transcend 64GB 600x For I have hesitated 2 seconds !!! Speed promises are kept. Remember to save your SD card from Transcend's website is LIFETIME !!! Yes Yes. I'm not talking about the delivery in max 48 hours and the quality of packaging is that Amazon is still PERFECT !!!
