Returned mine! While it has got some interesting features the image quality is poor even comparing to the gopro hero 5 session I've owned at the time. The biggest disappointment is the fish eye+ jelly effect due to 170C angle- it's just not pleasant to the eyes and look unnatural! Also, in order to use features like GPS, eCompass, Accelerometer, Thermometer, and Barometer in your footage you are limited to an app which is dead slow! My personal opining get gopro hero 5 series, YI 4k+ or stretch to hero 6! Thanks!
Not commenting on the deal price, but have had the camera for a year or so now (just checked black friday 2016 - paid £199 - so actually nearly two years later either I got a v good deal or I would have expected price to drop more), to be frank have been v disappointed, have used in snow, and snorkelling and diving, images are not as good as I had had with previous supposedly 'lesser' quality cameras. Just a users opinion.
I was watching examples on YouTube Inc a review, was good and that was at £279.
Look's cool & £100 off
