I've gotten a 128GB for $30 first. That makes more sense. Unless you have a massive collection of music, don't have data, want a copy of wikipedia on your phone, or never upload your photos to separate storage, you generally don't need the bleeding edge amount of storage. FWIW, I have Wikipedia offline on my phone and still have 60GB to play with.

Using this have had no issues with it what so ever.
