Essential for RN4081 users!
These cartomizers are everything I was looking for, very easy to refill and each can provide me with several days of regular use. My very first cartomizer out of the pack developed a burnt taste after a while, but I'm sure this is because I didn't top it off as I should have. To all who are interested in this product, I recommend topping off your cartos every 2-3 days or as soon as the taste begins to change. Great product and phenomenal customer service, as expected!
