Need help in buying a microSDXC

I want to buy a microSDXC for my new sony's mp3 player. There are different rates on marketplaces like ebay, amazon, etc as reviews confused saying that they are fake & some stated are real.


If anyone holding experiences in buying micro SD cards or knows genuine site(s) please share here & also prefer excellent brand.

you don't need really expensive ones for mp3 players
but if you are using it for capturing hd videos and playing than you need class 10 or Ultra 1 cards

I use Sandisk 8gb U1 on my lg g3 for UHD videos

you don't need XC, regular microSD will do.
just buy from a reputable seller on ebay/amazon.
