Except I don't bother with CL coils--CLRs only.
When I bought a whole bunch of the eGo One tanks from Health Cabin really cheap...they all came with the CL coil. So, I decided to use a few of those along with some of the CLRs I'd already ordered. Funny thing though, the CL coils last me usually at least 9 days each, while the CLR coils last fewer days...same juice, tanks, mods, settings, etc. I haven't figured out why yet. I think I'll use mostly the CLR now though and pull the CL coils for when I can't build any more.
