Olympus Digital Voice Recorder
I spend a lot of time in my car stuck in traffic. My most creative thoughts tend to come at this moment. I've almost killed myself several times texting messages to myself or even trying to jot things down. In situations like this, a digital voice recorder would be very handy.
Indeed you can protect yourself by using a digital voice recorder such as this Olympus brand recorder. It's great for professions who may need to record a conversation to review at a later date, whether it be a doctor or home inspector. They are also great for protecting yourself in legal matters.
