i need some ideas as to whats going on with my Romeo Plasma/Fires. I took some close-up pics of the serial and noticed a faded number above. the 001881 matches the box but i cant understand why there's another number. the number on the box has a 'B' before it as well. looking on o-review there was only a second gen with an 'A' before the serial. the box has a bar code which suggests it is a later model. thanks in advance of your replies!!
