So glad I found this product after trying so many different ones, this is the best one I've had. For me I am sensitive to the pg ecigs so to be able to get replacement e tips that are only vg and contain no pg is such a relief to find. Only criticism is that the v pure tips are not available in many local stores like the other flavours. I think it should be advertised more and promoted to stores for people to realise that there is another option for people that can't use the pg ecigs
