Well the vv3's have the internal, integrated battery -- and a couple of mine are right around a year old, one just over, one just under; that first one was my exclusive vape for quite a while, until I got the sigelei zmax, so it's seen some pretty hard use. The 2nd one, I don't actually know if it's losing power, haven't tried it recently, it might still be ok.
The Vamo, I have no idea what's up with it, but its mode that corresponds to RMS just doesn't get the job done, so I went to its "AVG" mode, similar to Mean I think, and it works fine that way.
I did see the comment about the Zmax being a flat-top, and that's a good thing, though I have no earthly use for a protank. Since going to Kayfuns, I just can't make a clearo work at all anymore -- all of mine are in the "retired" drawer now. They might get PIFed one day, but I don't think I'll ever use another clearo; they just don't compare to Kayfuns in any way, shape, or form. The only "old tech" that i still find workable at all are cartotanks, but I got tired of the replacement cost of the single-coil, 3 ohm, punched cartos with the flange -- the ones without a flange won't work in my cartotank, so doing the self-punching to save money isn't workable. So my cartotank is also as good as retired. Think I'll just stick with my KFL+'s, the price on those has fallen a lot since the newer v4's came out.
