Good idea. Have you ordered the standard housing or the dive one? If you ordered the standard one hopefully you will get the new version. I read a lot of reviews that the old standard housing opening latch is tend to break. I think I will order a gopro dive case from amazon, and buy a polarpro maybe the switchblade or just a polarpro red filter. I read somewhere that gitup will make a compatible red filter to their housing, but they don't have an official app either, so we could wait for ages until they make a red filter for the gitup housing. They have the gitup 1 which has the same housing, so they could make a red filter if they would wanted to.
Anyway, which firmware do you have on your gitup, because mine has the 1.3 and when I go to custom wb and play with the red and blue numbers, nothing change. The colour is the same with red:1, blue:1 and red:9 blue:1 or red:1 blue:9. Also I noticed when I set the wb to red the colour of the image is rather orange than red. My setting is vivid setting, because I like the saturated colours. Have you noticed the same thing? Otherwise I did a test video outside in our car which has a quite dusty windscreen, and the colours are just amazing, so I don't want to return for this reason. It is maybe just a software issue.
