I just recently bought a whole bunch of Kanger Evods. I really like them for my everyday vaping. I mean, I also like to use a 510 Atty, and sometimes I whip out the carto tanks(but Im out of Boge XL carts for the time being), or even just use a carto on its own.. but more often then not, I use the Evods.
I originally purchased I think like 8 of them from My Vapor Store. All different colors, including stainless.
They all came with Kanger Pro Tank heads installed, except two.
Then, I purchased another bunch of them from MBV.
Every single one of them from MBV came with the old "Evod" heads.
I also grabbed replacement heads from both vendors. ALL the replacements are ProTank heads, or now, "Evod/Protank" heads. MVS lists the two seperately but are apparently the same thing. MBV calls them Protanl/Evod heads.
My experience has been simple.
the PRotank Heads work better overall. But, on thicker juices, removing the top wick helps a ton. Actually, it even works nice on regular juices too. The Evod heads, for whatever reason, just dont seem to produce as satisfying a vape as the protank heads.
However, one thing.. when you remove one of the top wicks, the Evod will leak when the juice level gets low. Seems to be fine when first filled and about 2/3 of the tank, but towards the end, it will leak like crazy.
But overall, I think these things are really great.. just the BCC design in general. They DO mute the flavor a bit as compared to a simple 510 atty, BUT, not a whole lot, and for what you get in terms of hassle free use, its not a bad tradeoff.
Id like to try some other BCC designs.. Ismoka BCC Tanks, Davide', and of course some Protanks.
