Only had it a few days, but so far it seems to work fine. One thing to be aware of - the adapter came with the little slider switch in Write Protect mode. I could not write on the memory card from my laptop because of that, and almost embarrassed myself by asking Sandisk for support - the I realized what the problem was. I give 10% of the blame to Sandisk since the slider has no visual indication at all. A little dab of white ink would gave helped. But mostly, it was me :-) Anyway, just be aware of this if you use the adapter.
