Didn't realize until it was out for delivery that there were so many negative reviews so I came home hopeful but with the expectation that this wouldn't work. So I plugged it into my Switch and it showed up with 249 GB free. I was ecstatic. I started downloading games onto it and it was going along fine but I checked in and there was an error saying a corruption had been found. I went back and checked the amount of space on the card an when I calculated it again it had a large block filled up but the amount of data didn't add up. 3 games had finished with around 15-20 GB downloaded it as now showing 70 GB available and nothing else would start up to download. I deleted everything off of it and I'm not planning to mess around with it again. Lesson learned. buyer beware. if a deal seems too good to be true it probably is best to look a little closer.
If I could give this product a 0/5 stars I would do it. As soon as I received the product it gave me problems. I tried putting it in my computer with the SD card adapter provided,it didn't work. Tried it in my carmera, didn't work. Tried it on my Nintendo switch it didn't work. Bottom line is that this product doesn't work.
