wonderful product and best service by flipkart. Used it on Thailand trip, you can expect waterfull of activities, the water proof casing did the job and underwater videos are amazing. It's video are better then still, however, here I m attaching some stills.
thanks for equally good product then GoPro with less price.

It's an amazing action camera, picture quality is superb. Pricing is excellent. And I got it for 7199 from flipkart. There is actual no cons if u look at the price. But still an exeternal mic port would have been nice.

osum products... good quality

Superb action camera, best in the market. Sealed pack as bought it from a store. Awesome features and true go pro killer.

Good budget 4k action camera.

I bought this action camera on 24th July 2020.. Luckily Yi Action app is still working and I updated my action camera to Latest Firmware..New user interface is really good compared to the Older one..

No port for external microphone

Camera is excellent but you'll have a hard time finding it's accessories and even spare batteries.

This action cam is really good. All recording options are very sensibly programmed with good amount of control for the user.
However one concern that brings down its rating is Lens distortion, you cant get rid of it. Some lens distortion will be present in all wide angle pics and videos. Another small concern would be lack of social linking outside China. Only facebook and youtube are available.

The water proof case is nice as well and worth the money. It saves the camera from rain and splas...

something seems funny with the screen hopefully it's nothing serious
will keep the product if the problem is nothing serious
