Whats the difference between ry4 & ry5 from freedom smoke usa? I recently placed an order with them & they gave me a free sample of ry4 & I must say its really really awesome, just curious about the ry5 though, anyone know? Maybe its just me but when Im vapin ry4 I can taste caramel & peanut butter, more of the caramel though, what are your thoughts on it (to anyone that vapes ry4)?
