In May of 2020 I bought a 16 GB SD Card made by them on Amazon for my Nintendo 3DS. It was not a used product, as it was shipped with the packaging undisturbed. For around a year I had no complaints, it worked, until around July of last year when it was became locked to read-only not being able to modify it in any way. This left the SD card useless, and I bought a replacement from a different brand. The longevity of memory cards should not be this short, the only reason I am not giving it a 1 star review is because it was cheap, about $3, still I would not recommend this brand.

Do not buy anything from this company, it's a scam. They will not honor their manufacturer warranty and will not help you at all after spending hundreds of dollars on their faulty product.
