My wife's Razr M has been a great phone to date. I matched it with what I thought would be a great memory card, having been a long time Sandisk Ultra user in my photography.Sadly after 3 months, without warning, the card mysteriously "bricked". Unreadable by her phone, two PCs and one Mac .. the only thing that can even SEE the card is my Droid Bionic - which says the card is unreadable and needs to be formatted. I am hesitant in the very odd chance I can still recover the many gigs of photos and videos of our 6 month old baby which were not backed up.I could not be any more disappointed in this product.
