      No Good
      So I got this under the impression by the videos online that this was really concealing under the eye and it’s not…very oily and hasn’t done anything for under my eyes at all! Scam!

      Great quality!
      Style: Dual Dash Cam Without Card
      I’m really impressed with this dash cam! The video quality is super clear both during the day and at night — you can see details perfectly. The dual camera captures both the road and the inside of the car, which gives me extra peace of mind. Setup was very easy, and the screen is bright and easy to navigate. The wide-angle lens covers a lot of area, and the loop recording and G-sensor features work flawlessly. Great value for the price — definitely recommend this one!
