This was the first time I’ve installed a doorknob. The video included in the instructions made it simple. From start to finish it took me less than thirty minutes to have everything running! Would highly recommend.

It is adjustable in so many ways and the phone holder can come out so you can use it without it. So happy I ordered this one.

Most notable was the dramatic increase in range. Next was the longer play time - battery life. Last was the very excellent volume...it gets loud which it needs to be when I'm out walking. Thanks.

I will add to this list of pros and cons as I use the camera.Pros:*The image stabilisation is shockingly good.*Sound quality is improved over previous generations.*The ability of the camera to hold a higher range of contrast is improved over previous generations. It doesn't lose details in the brights or the darks.*The general build quality seems improved over previous generations.Cons:*This GoPro is considerably larger and heavier than previous go pros. You are going to feel it if it is attached to your head or on a long extension. This is the price for a front LCD screen as well as improved image stabilisation I think.

Good price (on sale), works great with laptop, but I had to buy a "splitter" with input/output plugs for it to work with my desktop.
