In NswSailor's recent thread about his failed hard panel, one poster mentioned a failed flexible panel.

When they first came out, I seemed to notice a lot of failure reports which scared me off, but they've been selling at reasonable prices for the last four years or so, and thus I am now re-thinking the prospect of trying some.

Before I do, however, this thread asks any members that have used "fully" flexible or "semi-flexible" panels for 2+ years what their experience has been in terms of breakdowns or gradual lowering of capacity?
