At this price range it seems like you can either go for 4k60fps with no stabilization or 4k30fps with EIS. I tested this product mountain biking and would prefer 4k30fps with EIS or even 1080p60fps with EIS. Although it all depends on how you use it. If you need this camera for slower motion like vacations or underwater travel, 4k60fps is probably more important than EIS. For fast and jerky video recordings, you should look out for EIS, otherwise you will get a headache when watching videos. HOWEVER - - If you have access to good video editing software, I'm sure you can stabilize the video a bit after processing, giving you the best of both worlds! The only thing you miss is image details with sharp cuts. After all, this camera is in its price range ($60) so if you can find it cheaper you get great quality. deal with it. Just make sure you know what you're using it for and adapt its features accordingly. For me this is not a crucial factor as I only use videos to show my friends some of the trails I ride. that they are too far away. I'm not worried about posting it on Youtube or anything like that.
