I have had a Nimrod for a few years and I love it, however, it does seem to be high maintenance and need to be refilled much more often than my Zippo. Even when it lights it often extinguishes on the inhale. I have Zippo flint and wick in mine and replaced the cotton to answer a couple questions above. I just don't want to have to carry lighter fluid with me every where I go. Although, I think you guys have motivated me to pull it out.
