In reply to wilf1234:
A Scorpio in the shops now should be fine, the batch numbers affected are on the recall notice here:

The thing about "reliance on stitch webbing which progressively tears" is that you have no way of re-setting it yourself after a fall. (Unlike, theoretically, something like a Zyper where the rope slides through a friction plate.) In the real world though, resetting a Zyper by hand would not be easy (about on a par with untying a fig-8 knot that an elephant has fallen on). The upside of the stitch webbing thing is that you get a much more predictable shock absorber than the other kind.
You won't tear the webbing just resting on it, it takes a pretty hard fall to do that. Personally, if I were off to do some via ferrata, I'd be perfectly happy to use a Scorpio.
