Been vaping for about a year and I started with V4L and still have and use the KR808 XL manual batts (380 mAh) - I ordered a
6v device about 3 mos in to get better performance out of the KR cartomizers (V3 w/KR adaptor) and it worked - and I've tried almost every carto out there - Here is my two cents for your situation:
- Order KR Boge Cartomizers (3 ohm) - I finally ordered these (cloudsofvapor and others) after reading alot about them and, trust me, nothing compares - I haven't tried the dual coil cartos yet (gotvapes.com) but for a single coil, the Boges just kick .... -
- Order a pack of ce2 R4s (clear or stainless - same vendors as above plus others - google it) - these are no more expensive than a box of cartos with filler - I can't tell you how well these are working on my KR8 batts (either the 2.4 or 2.6 ohm work great) - I've cleaned and dry-burned the coils on 5 of these at least four times and they perform like brand new every time - I've boiled, rinsed, dried with a small fan for 3 days, filled when completely dry and when slightly damp and never got my cartos to perform like when new - for $2, the e2s last way longer and after cleaning no different than the day you got 'em - I've got ten boxes of these and over the last 2 months I'm still using the same 8 clearos that I started with - btw, I remove all of the rings so no syringe - just drip down the side past the cup till full
I have not yet tried the CE2's. I am going to now though after reading this. Very interesting concept and design. Thanks for posting
