It’s a nightmare. I bought it and spent the day on the water with it with a two tank dive. It was the right size for me medium large , large. It has this really weird clasp system at the top of the tank and also the strap across your chest. It’s a hook system instead of the typical clasp. This takes some getting used to and while I was used to it, you actually have to look to see where the hook is going to go into the hole. It has a flimsy feel to it once you get it secured in place. I think Time will tell that this was a mistake in experimenting and they’ll go back to the way everyone else does. But the worst part is the fact that the tank seems to recoil from side to side. Meaning, when you turn your body while diving, even slightly, a half a second later the tank follows along with it. I have almost 800 logged dives and know how a tank should be placed on a BCD. I know you might think that I didn’t have it secured right, but believe me I did. I returned it. It sucks
