I really enjoy vaping when i get my equipment to work right but i am really tired of spending money on equipment that doesn't perform. I have looked over the site and I learned a lot but still have questions. I bought a blu disposable and liked the experience but wanted more vapor and more throat hit. Found a Bud kiosk at the mall and bought battery and refillable cartomizer. It was the small cartomizer with a flat tip. It had better vapor but was still very weak. I think I have an ego mega battery because it has variable settings of low, medium and high. I went back and bought a bigger tank from Bud and it worked better. Had great throat hit but vapor still lacked. It also leaked like crazy. Took it back and got a replacement and it leaks also. Bought a Cig2O and it had good vapor but not much throat hit. Bought a Blu recharge pack and it has the best vapor but really no throat hit without it being menthol. I put the cartomizer from the Blu on my ego battery and the vapor is strong but weak throat hit. It also burns up really quick. I want to purchase some type of cartomizer/tank that works on my batteries that produces good vapor, a throat hit and won't leak. I like refillable types and don't mind the size. I am not trying to quit smoking because I don't smoke cigarettes at all. I really like vaping. I just don't really understand what to buy to keep my battery that I have. Resurrector LR, phiniac tanks, single or double coil? I have purchased six different bottles of e liquid and only one is good tasting. The Bud really irritated my throat after a while. So, If I have what I think is an Ego Mega variable Volt battery, what type of refillable tank would anyone suggest. Any help or suggestions would be appreciated. Sorry for the long post.
