I know. I saw a review if the X4 yesterday..... very tempted! lol. However I'm not impressed with the durability of the invisible UW housing - scratched as soon as you look at it! Otherwise, a great camera for memories and social media
I'll be honest - I have not used the X2 so don't know how much of a generational leap it was between the X2 and the X3. I have however used the GP9.... and ditched if for the DJI Osmo Action very quickly. The 9 was unreliable, overheated and just too many times didn't record the footage. Apparently this was fixed only in the 11. Something to do with the processor used being too weak to handle the 4k shooting with all the image processing etc.
