While looking for the charging cord for my camera I stumbled across the last blu we had. it was the old 3 part style, and about a year old. the cartridges even still have juice in them. while they seem to have broken down a little over the year, they still have flavor and vape. I am charging the batteries at the minute, but the atomizer still works. if the batteries still work this means I have 2 more batteries to get me through the day, and an extra charger. I am seriously shocked that the old blu still works, and even more so that the atomizer isn't burnt up. yay, more things to tinker with!
