I bought this on October 9th and didn't start using it for about a week after I received it on the 11th. Well two days ago it died a quick death, I can't even format it! So after all these years of buying SanDisk products I guess I will give in and start paying a little more for Kingston it seems as though SanDisk is getting to be a cheaply built product. You would think that a product this small and inexpensive would be able to be replaced without cost within the first 90 days but that is my fault for not reading the fine print so lesson learned. Buy it right and buy it once so go with something else!
