Philippine Brand Calamansi Juice Drink

I bought this because I had never heard of calamansi. The back of the can says it's a Philippine lemon, but a quick Google search brought up that it was more like a lime. Either way, it's some sort of citrus fruit. I was hoping this was going to be really tart and sour, but sadly it wasn't. It's good, but it tastes like a boring citrus drink. There's nothing special to this. Although, I just realized this is the first time I've had juice in a long time. Maybe I should drink less soda and more juice? I doubt that will happen.
