“With the recent change in your product, I ordered and received two 60 mil bottles of the Menthol Free, which I have been receiving for a few years now. This time around I went with the 60 ml bottles, as the 30 ml didn't appear to be available. Although the flavor remains good and I'm pleased with that, I have found that this new product "burns" (if that's the correct term to use) significantly faster than previous products. Perhaps there are reasons for that, unknown to me and I am reaching out to solicit possible explanations or feedback from other users with similar observations, as I'm dissatisfied with the period of time my previous order is going to last. Thank You.”
