Pros:
- If there's what you can call double security, then this thing is on top of that term. Adds an extra layer of security to your devices...
- Mini, small, and so handy. Which will allow users to have their extra security with them, walking, traveling without worries.
- Just like regular USB where no one will ever have an idea what that thing really is.
Cons:
- Just one thing, if it's lost, you are done with your important devices!
- So you have to buy another one for another extra security. *sigh
- Then it will be costly on your side.
