sd card

My current digital camera had been with me for more than 3 years already. It is still very useful for me at this moment. Well, hubby said he wish to buy extra micro sd as he foresee the existing card may not long lasting. It is his perception actually. to him, any electrical item that had more than 3 years shelf life, then we got to be well prepare that it may gone damage or spoil anytime. He added that it is better to keep extra micro Sd. Now instead of waiting for it spoil already, and then only look for new one. Moreover the card is having promotion now. It is a good buy for him!
