This $25 dash cam might be your best car accessory purchase yet

Dash cams have become practically invaluable tools to have on the road. In the event of an accident or an altercation with another driver, a dash cam can be your best and only witness, and the Black Box 1080p Dash Cam is an excellent choice for only $25.

The Black Box features a built-in G sensor and motion detector, so it will automatically start recording in the event of a crash. It captures both video and audio in high definition 1080p with an impressive 120-degree field of vision, ensuring that no important detail is lost. 

It’s small enough to fit securely on your windshield with the included mounting bracket without blocking your vision. When you’re ready to view your footage, you’ll appreciate that it’s compatible with most operating systems via a USB 2.0 connection. And it has your back day or night — because what good’s a dash cam that doesn’t work at night?

Normally the Black Box sells for $149.95, but Mashable readers can take 83% off and get one for just $25.
