Ok, I've had one for several years. I lost considerable weight (over 30 kg), but then started gaining again. I though I was just eating more unhealthy food. BUT, I recently found out the band was broken. I had surgery to fix it a few days ago. I heard of another person having it "fixed" the same day as me in that hospital. By broken I mean: the tubes connecting the actual band and the port have somehow been disconnected, and the fluid came running out, deflating the band. Did anyone have this happen before? And how common is this even? Granted, having it fixed was not a tragedy, but it does mean surgery again. Is this a manufacturing flaw? What can cause it? And more importantly, how likely is it it will happen again?
