I’ve been asked several times for feedback. Firstly, and positively the delivery is first class. I’ve spoken to customer service a few times and they have always been helpful. I’ve been purchasing Ok-ecig cartomizer refills with rechargeable battery since June last year when Greensmoke stopped suppling the UK. Negatively I normally purchase the 3-month bulk pack deals which lasts me not quite a month, so I must be a serious vaper. I notice that if I open one shortly before I go to bed the next morning it doesn’t last long? I strongly disagree with Ok-ecig claim 5 refills equivalent to 125 traditional cigarettes, I was a 20 per day cigarette person and I’m using up to 3 refills a day. Regarding the rechargeable batteries, I purchased the new K2 ultra in January I ordered two to try them the grey tip came off not long after using the K2. I spoke to customer service Alice and she sent me a replacement thank you, however since then I have placed another order for one more as all the other three grey tips have come off, and so as the latest. With all the K1’s they have never come off not one? It surely does not just happen to me? I read the feedback from other Ok-eig users and no one as mentioned my problems. I still use the leather carry case I purchased from greensmoke, could Ok-eig start suppling them? I’m 65 years old and with the help of Ok-eig I’ve been off cigarettes for five years.
