GoPro is one of the most popular brand of action camera. GoPro Hero 4 is one of the best camera compared to all action cameras. It works properly upto 4k resolution. Also take very good slow motion videos. It works properly at low light condition. The 12 mp camera takes very good colour reproduction, but overal you didn’t expect like DSLR but it works nice in this price sagment. The camera is also water resistant, you can take videos under water also, but the cameras lasts very short time for the cheap hardware. Overall it is value for money product. This product is for the video bloggers for making videos at any time any where.
