Hi Debzcf, I am so on the fence with whether to get another VV or Grand. I've got them both and they both perform so well. I'll be honest about the "wheel". Once I found the sweet spot, I stopped playing with it. That's not to say it didn't have it's place, it does. It helped me find the sweet spot. However, it makes me wonder; If I can find the sweet spot on the VV and then build the coil accordingly for the Grand, then I still got a good unit. I've even thought about prebuilding coils and just change out on the fly, or (this could get expensive) just have some extra RM2s. As I look at all of this though, I ask is all this trouble worth the extra fifty dollars. As far as the battery retaining a regulated charge? I thought I would have problems with the Grand, but I'm not. I just change the battery when things get weak. Hell, I'm going to buy an inline meter and stop guessing. Not to sound so deep, but then I began to think about "What trouble am I having with the plain REO; NONE! I came from the world of Provari (only a short visit before I found you guys). A world where I had buttons for adjusting and checking batteries. A world where adapters were required for EGO tanks. A world where I could turn the LEDs on or off. A world where I was given options. However beautiful that world was, and still is for some, I could not do one thing that the REO can and still does without fail: I CAN PUSH ONE BUTTON AND VAPE! The Provari required five presses, and then you had to make choices or types of tanks. What voltage am I going to vape at? Am I going to use the bottom fed tank or the VIVI Nova? I had become so consumed with options, that it detracted from the reason I bought the unit in the first place;
vaping.
Anyway, not to get off track or take away from your thread. Yes I do appreciate the VV for it's glory, but I also respect the Grand for it's simplicity. Ultimate solution, since this has become a obsession, I'll just keep buying both and even more when the DNA2 comes out (and I'm sure it will).
