For the money, its worth it. I purchased one for myself and one for my husband, my husband's up and quit on him and i had a refund for it within days and replaced the one that broke. Its good to have almost all the angles covered, being recorded. Its not the best quality but its lasted long enough that its paid for itself. It can take larger micro sd cards than what it comes with. it will lock files if the car is jolted too much like hitting train tracks or something. But its records over the oldest video and yes it does record audio. This feature has come in handy with kids and phone calls. I approve!
