Its really not worth arguing over. It is what it is. But most of my Oceanic experience is with an older Veo 100nx. Just setting the FO2 is a pain and there is no easy way to simply glance at the screen and check the current setting. And not only does it reset after the 24 hour period but each time it is activated. That means if you are not in a desaturation period and set the gas while checking your gear before leaving for the dive, there is a fair chance it will shut off and you will have to reset again before you drop. All in all a real PITA that I just don't see a need for.
