I like the build quality and ml size of the v12 prince. But find coils are overpriced as they dont last long. Thinking bout buying a freemax mesh pro as heard the coils last ages.
Do it, and get the double mesh coils.
I'm an avid lover of Smok gear, but not for most of the coil types they do. As others have said, well done on getting more than 4 days from a Q4. I was using the mesh coils in my V12 prince, but even they where hit and miss, although far better than the Q4 one's.
As far as the freemax mesh pro goes, the reviews where all good, so I bought one. (blue resin 1, to go on me blue resin smok majesty, perfect match)
And yes, the hype is true, the mesh pro is in a different league to my well loved V12. Despite the amount of spare coils I have for the V12 (bulk buy fasttech) it hasn't been used since the mesh pro arrived. It's now in the spares box, with all the other once loved gear.
So in a nutshell, if you like the V12 prince, your gonna love the mesh pro.
