These bindings are fairly good, feel solid and definitely are way better than trekkers. However, they have several short comings. These bindings are still touring bindings, and cannot withstand the abuse of alpine bindings.
On the skiing side:
The rivets that attach the binding to the climb/ski latch are pretty weak. Mine have become lose and I get significant for/aft play in the binding in ski mode.
The toe piece has a pre-release problem. This may or may not be due to the fact that the height adjustment moves around a lot making my toe creak a lot while I ski.
This makes me feel like the bindings are neither strong enough, nor reliable enough to be have dins springs that can be cranked to 16.
On the touring side:
Pretty good. However, they can get clogged up with ice really easily making them very hard to change from ski-climb mode if you do not skin with your heel lifts up.
