Bests & Worsts Reviews from Amazon

I don't usually review products, but this is a fake product. It is disguised as a 512 GB drive but any files/pictures/videos after the 56 GB mark are corrupted and won't display properly. I have also scanned the product using h2testw and it supports this claim ("56.5 GByte OK" and" 443.3 GByte DATA LOST"... - see attached image). To the people who have left positive reviews: I urge you to review all your pictures and videos are actually there. I initially bought this product to back up my mom's 128GB iPhone photos and videos to free up space. She would have been devastated if she lost the photos and videos.
