Due to the shortcomings of e-cigs, after many months I feel obliged to look for a mod. My citeria is: optimal voltage for the 510, longer batt life, and less voltage drop. Maybe some of you folks can help. What's important to me (and I suspect others) is: 1. Voltage in the 5 v range without drop. 2. Protected batts. 3. Not TOO big. 4. Long batt life (but not at the expense of a huge piece...a trade off) 5. batts that can be purchased anywhere. 6. quality switch & components. PROBLEM is, the web sites that sell these mods give very little product description. I'm hoping those with experience can offer advise to those of us who are just looking for better performance. As far as I can tell, and that isn't too far, the Prodigy2 MAY fit the bill. Thanks in advance of your response.
