This is my first foray into dash cams. I was always turned away by having to attach something to my windshield and have wires sprawled about my car and having my outlet being used 100% of the time.
I normally only use electronics made by companies I've heard of, or heard things about. I've never heard of Rexing. I was a bit skeptical. The device itself is well made, with lots of buttons (that weren't too confusing) but at the same time, the design seems outdated. It's not bulky, but it's bigger than other dash cams I've seen and bigger than a GoPro. But again, it's well thought out and that's what counts.
You can easily tilt the lens while keeping the device up against your windshield.The screen is nice and bright, although after using it a few times, you kind of forget it's there and it becomes no big deal.
It comes with ample cable length to hide them in the interior. As I stated, one of my big gripes was having cables going every which way in my car. The power cable for the main unit, and the one for the rear camera are plenty long. I was able to use the included orange tool (I'm honestly not sure what it's for, but I used it to wedge the wires in the interior molding). It took a little time, but it was so worth it. Now I have the camera on my windshield and virtually all of the wires hidden.
The instruction manual is extremely useful and easy to understand. I generally don't study manuals but this one I did so I could better understand how to set up the dash cam. Having an easy to understand instruction manual was a plus. It walks you through the numerous buttons on the main camera. This is necessary since their is no touch screen (non-touchscreens actually feel nonintuitive these days).
Once everything was set up I was extremely pleased with the performance. One of the most important things you need in a dash cam (in my humble opinion) is quick start up time. This baby fired up and started recording almost immediately; within seconds. Mine is set to record in three minute clips (on 32 GB card, once it's full, it rewrites everything). I effectively save about 3 hours of video at any given time. That's more than enough should you decide you need any of the footage.
I haven't been in a wreck, so I can't comment on any of the emergency features, such as change in gravity or recording in an emergency with loss of power, but I did review the footage on my computer and was surprised with the quality. This is full HD, not old grainy footage from the show COPS.
My big gripe is the sticky adhesive used to mount it to the dashboard. The device itself is supposed to endure high temperatures. While I parked my car in the hot sun (in KY mind you, not AZ) the adhesive came undone and when I got back to my car the main camera was dangling from the cord. Luckily I pout it back on to the same adhesive pad and haven't had any other issues, I know it's a matter of time. And while I'm sure I could find another adhesive pad, I feel like I'm going to be having the same issue again. What I would have preferred was a suction cup mount. I'm sure it would add to the bulk (at least the distance the camera comes off the windshield) but it would have been a better long term option in my opinion.
All in all, this is a well thought out dash cam, especially regarding its features and design. I only wish it had a better long term mounting system so it doesn't come off the windshield on a hot day. And most importantly, the footage quality is great.
