“RY4 is my one and only ADV flavor profile. It's what I started on in 2012 and will ever be. I've tried dozens and dozens of different brands version of it and this one by Mr Salty is not only the worst excuse of an RY4 I've ever had, it's also the worst eliquid I've ever tried. It not only tastes acrid, it stinks like nothing I've ever experienced in vaping. Hard pass on this.”
