John asked if I would be willing to start a thread here at HDV about RBA's and as I thought about it I decided to start with why would anyone want to buy one. A little background is in order here to explain how I found HDV and RBA's. I have been vaping for a little over 2 years now, I started with Ego style batteries and pre-filled carts. I quickly found that I could save $ by refilling my own carts so I began ordering juice and refilling my old carts. I used to have to replace my batteries every couple of months or so, I dont know if I just always got bad ones or if the frequent power fluctuations/outages here in FL shortened their life but I got tired of constantly buying new batts not to mention always worrying about being caught without a working batt. This is what brought me to ECF, i found it researching how to take the next step in vaping. I have always looked for the next step to take to make vaping either less expensive, more reliable and more enjoyable. I found HDV researching DIY in order to bring down juice cost and have ordered all my DIY juice supplies from John since then. I had settled into Boge cartos in some of Johns hand blown glass tanks as my everyday method and was really satisfied for awhile. I was getting about a week out of a carto at first and the cost was reasonable. Then Boge quality control fell off a cliff, I was lucky if I could get a day or two out of a carto at the end so I went in search of something else. I ordered a DID and since it arrived, about 3 months ago, I have not touched a carto. RBA's have a definite learning curve and are not for everyone, they can be a little finicky and frustrating at times but when you finally get that perfect wick and coil dialed in the taste, throat hit and vapor can not be beat. So far I have not found out how long a SS wick will last as I have changed them out just to play with different wick materials and density. The coils, so far I get about a week out of before I change them out as they get gunked up. I would try cleaning them but at a few cents per coil, its just not worth the time. Thanks for taking the time to read my ramblings. I want to thank John for now carrying RBA's and supplies along with all his other great selection. I will say I am not an expert at rebuildables, there are others that are much more advanced than myself, but I am more than happy to answer any questions that I can or point you in the right direction to get them answered.
