New Stop, any good?

The new Stop appears to actually be out in the wild now looking at Inglesport's website. Has anyone used one yet, any good or bad reviews?

There was this discussion: https://ukcaving.com/board/index.php?topic=24585.0

Review of some club members who tested the new stop during the anialarra expedition.

Bottom line, Some good  improvements but the bobbins do wear and can?t be replaced. So for hardcore vertical Cavers it will become expensive.
