I bought this from USA this is better than Gopro in terms of quality, price, the number of free accessories with the product (with GoPro you need to purchase everything additional) Great value for money and quality. GoPro is only marketing but this is what an action cam should be!!
It's a great piece of technology at a very competitive price. I bought it over GoPro because it offered free accessories with the camera. The quality of recording is just top notch and it's fun to use. Waiting for my Andaman trip to test it under water.
This camera is small, smaller than the size of your palm. Makes one nervous to handle without the casing and mounts. The accessories that come with the camera are good, but pretty useless cause you need to buy straps to mount them safely on. I, personally, don't trust the 3M stickers to stand up to the wind resistance offered while riding a bike. Picture & video quality in general is brilliant. Saturation, Brightness & Contrast are all perfectly well balanced. Although underwater picture & video is not so great. Wifi app works perfectly well on my Nexus 5 and comes quite handy as well cause 2" screen on the camera is really difficult to view on, especially under sunlight. Overall, I'd say it's a good buy, especially compared to GoPro. And all GoPro accessories and mounts fit perfectly well with this camera. ISAW accessories are of poor quality though. Would recommend finding suitable GoPro accessories to use along with this.
In terms of specifications, it beats go pro which makes it sound like a logically better choice. However, the e3cosystem is not developed fully and therefore the app associated with it is not up to the mark and neither is the water proof mount that has a tendency to break. The power button has stopped working smoothly now and I have to press quite hard many times in order to switch on /off the camera. I would recommend going for gopro session.
