Hey!
I have tried and had much success with a KangerTech EVOD Bcc ($4.95) and an iClear 16 ($4.45)
KangerTech EVOD eGo 1.6ml MT BCC added colours (Metal Bottom Coil Changeable) Clear Kanger cartomizer/Clearomizer
Innokin iClear16 V2 Dual Coil Clearomizer
I prefer the EVOD because it has a lighter draw and I find I get more vapor that way. It is also bottom coil as opposed to top coil like the iClear 16. That is more preference though.
I haven't had such luck with the ProTank II ($16.50) unfortunately. Due to leaking issues, I've abandoned it all together. Maybe I got a dud, but its either a love it or hate it clearomizer.
KangerTech ProTank-II/Protank-2 BCC
Honestly, the EVOD BCC is so good you should atleast try one. It used ProTank coils so you can buy 5 packs for real cheap and keep changing coil heads. Works flawlessly.
If you decide to purchase an EVOD, check out the 1.8ohms. I find with an eGo style battery that I get burnt taste out of anything above 2.2ohm, no matter which clearo I use.
I just received the Mini Protank 2 and love it so far.
New! 1.6ml KangerTech ProTank V2 Mini BCC(Bottom Coil Changeable) Glass Cartomizer - Vancity Vapor est. 2010
It's got a 2.2 Ohm coil on it and I have an eVOD battery on it. I'm thinking about getting a mod because I usually smoke 18 mg and the bottle I got along with the Mini Protank 2 was either really harsh or it wasn't mixed properly. I definitely had a lot harsher hit on the throat and it just felt wrong. Not sure if it's the voltage or wattage. But I definitely would recommend that tank if you're looking for something that isn't leaking. Oh it's only 1.6 mL tank as well.
