I came back to vaping Oct 2013. I got into RBA's about 6 months ago only due save money on pre-built coils. I found the vape quality was so much better. I only rebuild due to necessity. I've been on a quest to find a clearo that comes anywhere close. In the last 6 months I've tried almost every Kanger and Aspire clearo that's hit the market, except the Altantis. I have found them lacking and have either resold them or PIF'ed. I only bought the Subtank, because it had a rebuildable deck option. It came preinstalled with a 0.5 ohm coil, so I thought I would try that first. That was almost 2 weeks ago. I'm still on that first 0.5 ohm coil, and it's going strong. This is definitely the first clearo I have found that comes even close the the vape quality of an RDA.
For a new vaper I think the Subtank Mini is going to be the best of both worlds. Fantastic pre-built coils and the ability to try the RBA section without committing to an RBA. The coils are higher prices than other coils, but the actual cost is so much lower. Other pre-built coils I used in the past would typically last a day before getting gunked up. I tried all the various methods to clean them, but it really didn't work. I can't believe that the first Subtank OCC coil is still going strong at almost 2 weeks!
