Synergistic Tesla Powercell 6

I bought this 4 years ago from the original owner. I have the original box, manual, white gloves and Mini Power Coupler (MPC) that is the 1 lead configuration. I bought it without a Synergistic power cord. There are no scratches on the unit from my use or the previous owner's use. There is a 7/8" long blemish that I tried my best to photograph. It is what looks like a "smear" of glue from the factory. It appears to me that the black plastic case is made up of side, back, top and bottom pieces that are joined together with a specialized glue to make the cabinet. It looks like a little bit of glue got away from the technician when it was assembled. It is very small: about 7/8" long and it never bothered me and I am picky. I looked at it as a birthmark :^) Anyway.....following my rules of full disclosure, I wanted to be up front so there would be no surprises. If it wasn't for this small imperfection, the unit would be rated a 9. You will be very happy with its performance and cosmetics. It will be very carefully packed in the original inner and outer boxes
