I got myself 2 cheap SD cards, now thats a regret. Amazon is full of 2 packs of them which tempt you into buying. Seeing you get 2 cards instead of one seems a steal. Never again lol I have just went to use 2 I got 1 month and 10 days ago from a brand called Kexin and both are not working. I have tried them in another adapter and windows cant see them or the Zoom h5. They have barely been used over the month too. I usually go with Sandisk and issues like this just confirms why I choose them over other brands of SD cards. I used to buy Kingston RAM years ago so tried their SD cards but I had similar experiences with data loss suddenly. All memory cards eventually fail but when you buy cheap and think youre getting a bargain you are often just outside the 30 day amazon return window lol 
Have you ever had an SD card fail on you? I was so lucky yesterday with another of mine pulling the data off it using DMDE recovery software. Which brand of SD card do you use and trust the most?
