I haven t tasted Hangsens RY4 eliquid, but this one is without doubt the best I ve ever tasted, both DIY and mixed. In fact, I couldn t understand the hyateria around RY4, I used some eliquid in several of my mixtures after experimenting a bit, but I couldn t imagine vaping it alone. Now it s one of three mixtures I vape 99% of the time, and I m really looking forward to try out Hangsens eliquid. It would we very weird if my homemade one should be better.. One of these days a tasty surprise will be picked up from my mail box, and that day it will almost be a ceremony:-) And to me it is a big plus that it is an organic product! Buy and have a great vape!
