Well I had a little issue with my Switchback from vaporbeast but Tim from vaporbeast is an awesome guy! really went above and beyond resolving my issue. 16 days analog free!! I feel so much better, I noticed that I am not whizzing anymore in the morning whenever I wake up and the biggest improvement that I notice is my blood pressure. I usually hover around 147-97 mild hypertension but lately I've been getting around to normal range, 127-83! Also, I used to love the smell of cigarette smoke, now whenever my co worker smokes outside the shop the smell is just disgusting and I can smell it from a mile away! lol trying to get him into vaping also.
