I purchased this unit to put on my motorcycle for taking videos of my ride.  Here is my initial impression.Size - Smaller than I anticipated and very light weight.Fit/Finish - Very nice feel to the unit.  It does not feel cheaply made, the exterior is metal and seems to be durable.  The only flaw I really thing this has in the rubber rear cover that caps the switches that adjust the video settings and where you put your MicroSD card.  Kind of cheap feeling there but no issues to date.Performance:Video Recording - Works very well in daylight or moving into evening use.  This has a very wide field of focus.  What I mean by that is: I first used this in my truck.  I mounted this on a RAM mount on my dashboard and placed the lens almost touching the windshield.  Ran the video for an hour or so and on playback, I saw lots of hood as well as my drive path.  You really need to experiment with camera placement to get more of the scenery vs car/motorcycle body parts.Have not tried low light recording but night recording plain is non-existent but then it is not an infrared camera.Battery performance - Very good.I recorded four hours of SD video with no issues on a 16gb card.  I am still playing with settings on best usages vs footage.Sound - it will record sound (got my radio as some background music in my truck) but not loudly and really isn't designed to capture it well in my opinion.Accessories:There are several types of mounts.  You will want to get an extension arm if you plan on using this inside a car so that you can maneuver the camera easily on the dash.  RAM makes some mount accessories as well that I have used for my GPS and Cell phone on my motorcycle and car so I stuck with that so I would not need to buy different vendor stuff.  Check around for your best choice of product.Overall Impression.  A good buy.  I am looking forward to springtime for some mountain riding and see how well it captures the twisty roads of the Blue Ridge Mountains in the spring bloom.Good luck.
