Xiaomi Yi 4K Action Camera 2 : Price & Conclusion

Now, the big question which is on the mind of most of you is about the cost of these cameras. Xiaomi Yi 4K Action camera 2 is listed for $249.99 and GoPro Hero 4 is listed for $449.99
Yi action camera 2 which is on preorder can be bought from Gearbest’s Website and GoPro hero 4 can be bought from Amazon’s Website.

GoPro is a reputed and well established brand, which has thousands of users worldwide. However the sales have declined over the past year because of its non professional business strategies like its recent increase of one of its product price and delayed product launches of its drone and Hero 5 action camera. Another significant reason of its declining sales is that, there was no serious competition to its action camera line up until now. Many competitors are entering the market, with more advance features and competitive pricing. Xiaomi has taken this advantage and launched its product with new features and serious pricing.

To conclude I would say that the new Yi 4K action camera 2 is for anyone, looking to buy a powerful 4K camera with great features and accessibility. The camera costs half the price of its rivals and is a great investment considering all the features and a big battery.

  1. Such a great review. I liked the thorough comparison between the gopro and the xiaomi. I was looking for a camera to start making quality videos for my own website and although these two cameras seems to be great – they are for action cameras. Do you have more of a “standing” camera to offer me?
    Thank you so much!

    • Hi, thanks for the comment. Glad you liked the comparison review. These cameras apart from being action cameras are also good for occasional recordings or vlogs. However if you are looking for something different like the ones used by professional website streamers, the popular choice is usually a DSLR camera. Those will cost you around $500 to $1000. Otherwise an action camera like the GoPro Hero Session would do just fine and costs under $200.

  2. Awesome reviews on tech stuff, very comprehensive and in depth.
    You cover all the areas I could think of and answered all my questions. You have interesting range of product reviews.
    Can you tell me, will you be doing more comparisons like you did on the Xiaomi vs GoPro? I would like to see more on cameras and phone if possible. Especially the Chinese phones.

    • Hey,

      I am glad you liked the review. I will definitely be doing more reviews and adding more products. I haven’t thought about phones but if the audience would like see them, I would be happy to add those.

      Have a nice day :-)
