The SanDisk Memory Zone app I had downloaded on Google Play within 5 minutes, after which I could pull the images directly to the stick. On the hard drive, the device is recognized immediately and so the transfer was painless. The stick is small but well made and I'm considering now even the 64 GB version zuzulegen because I really shoot a lot of pictures, especially on holidays.
I would recommend to stick good conscience.
