I have been looking for a cute and portable, more of a pocket-size, calculator for sometime now. I am so happy that my hubby gave me this small Canon mini key chain calculator. It is just the right size for me since I do not want using my mobile's calculator function because of the small and quite embedded keys. This small calculator has great keys and they are protruding which is easy to tap.
It comes with a nice key chain lock which you can open and close. It is not the typical circular key chain which you have to budge with your pen or other key just to pry open. This one has a small tab on the side which you can press to release the lock so you can put it in your key's hole or clip to a bag handle.
This small little gadget has a lot of functions for its size! It has percentage too. It comes with one alkaline battery type LR 1130 which has 3500 display hours. Not bad for its size huh!
