This is a 5 minute Audio/Video Quality test taken by me.

Video quality is slightly bad since I had to render the video in Camtasia Studo from a 850mb AVI file into 150mb MP4 file.
I ordered a HDVR-150 Dash Camera for the sole purpose to legally protect myself in the case of an accident. As you can see, this dash cam provides excellent quality. Worth the price.

Here's my Amazon customer review:
5/5 stars:

I WOULD RECOMMMEND IT!! Very useful if you want to legally protect yourself in any wrecks.

1) After ordering, It only took (for me since I live in North Carolina, US) 8 Days just to arrive when It stated that it was suppose to arrive 4-6 weeks! That's fast shipping!!

2)the package came in a box. I opened it and found another packaged box, well wrapped in bubble wrap! Attached to it was a personal thank you note from the seller to me ;D very thoughtful that you care about your customers!

3) The product was amazing. Anti-glare, very LONG rear-view mirror. Very lengthy cable to use. 2 Suction cups and 2 clamp-on on the back of the product. VERY EASY INTERFACE and easy accessible menus. FREE 4GB SDHC CARD!! Very very very thoughtful! ;)

4) In my case, I drive a Ford Focus 2005. My device turns on as soon as I plug the charger into the socket whether my car is on or off. But that really doesn't matter to me, I'd prefer that I choose to plug it in. Same thing when I turn off my car, it remains on until I remove the adapter from the cigarette lighter socket.

5) Video 4/5 - Very Good quality video. Fish-eye lens makes it capable of viewing across your dashboard. Frames sometimes drop and lighting dims at low lit areas. Also, you are not able to see the license plate of other cars unless you are very close or parked behind a car.

++ Each file is 5 min long (about 800Mb if recorded with audio and video @ HD 720p 60Hz) and there is virtually no lag nor video skipping when starting a new file and resuming recording after 5 minutes

6) Audio 5/5 - Masterful audio. I was rolling down a street at 75 MPH with my windows down. Only MINIMUM wind noise can be heard. Radio/phone playing music can be heard crisp clear. Voices can also be heard if only projected in a high voice. You can barely hear whispers and low projected voices.

OVERALL, product is "Easy and Forget" where the installation is easy, wires can be hidden, no bulky camera in the view of your dashboard. Easy interface. Easy on/off. Sexy look for your car XD (in my opinion). Skype (Account name): iam_master_rambo
