2.8 - 3.0 ohms is standard? What about battery, will I have to buy another battery for a few days or week? How long do you have your without buying another?
I have had mine for about 1 year. I don't use it every day, just when I go out and need something like it. Yes, 2.8-3.0 ohms is standard. Another thing, don't try to charge a Blu battery with anything other than a regular Blu charger or the PCC. Most people on here do not consider the Blu to be a "good buy" because of the cost versus battery charge, delivery systems, etc. But, if you need something you don't have to fool with , is very portable, and somewhat stealthy, I can say the Blu has server me well. And I have several large ecigs, including mechanical mods and variable voltage devices. Other than battery capacity, if you are going to use cartomizers, it performs okay in my case, but remember, you will have to recharge it fairly ofter compared to larger ecigs.
