I was banded in 2003, in Texas. I have the 4cc band. I have had no problems what so ever with the older band. Just went in for my NINE year followup. Everything was perfect. No slippage, no pouch dialation, no erosion, everything was great. I have met my goal, then recently gained about 15 pounds back, so she added .7cc to the 2.5cc I already had. So, now I am at a total of 3.2cc. Hopefully this is what I need!
