Everyone talks about it, so I thought I would give it a shot. I purchased 2 flavors from myvaporstore.com. One was Mocha which is yummy, but the RY4 tastes like cotton candy to me, way too sweet. I don't seem to taste any caramel or hint of cinnamon like others say. I know there are different variations on RY4, but I think I would have to try too many to find the right one!
