Its better if you buy SanDisk Cruzer 64 GB PD without backup Button option. You can use much better third party softwares.
Since the product comes with a 5 yr replacement warranty it sounds very good
the best among all usb 2.0 pen drives with auto backup facility but transfer rate is not so fast. you can always rely on SANDISK brand.
When you dont' have a lan network, cannot afford to carry around a huge hard disk where ever you go - your choices are limited to 256gb, 128gb, 64gb, 32gb pen drives. This one was an obvious choice too. I had to get this sooner or later - Made my life a lot easier - I peek into my friends computers and find a few big isos 7gb or more. I plug in copy and before you know it you got it - no cables needed, no internet needed. Just quick and easy
It works fine with Windows 7 32 bit but it does not get recognized with Windows 8 64 bit. Also size should be small.
