Item purchased on 1 April 2011. Used in my android smartphone. Worked fine until today. Probably responsible for application crashes in recent months (crashes which I attributed wrongly to the applications used. Eight months later card unusable. Lost data (I'll try to find a way to recover but I have little hope).
I contacted the seller to assert the lifetime warranty of the product, but I'm not sure to reuse a card of the same brand to store important data.
