This is a 5*+ award (out of a possible 5) – it is just brilliant idea. Lovely rugged rubber around it feels quality. Keypad and access very easy and works perfectly. Absolutely lovely to know that ones backup data is PROtected. A truly brilliant Product. I have struggled with encryption for years, software encryption is a real pain. This keyboard device is just brilliantly simple yet so secure. A must for those wishing to keep their data safe on a mobile basis.
