Great In Bounds
I love these at the resort. They definitely are a lot of help in terms of controlling a fat ski. The only problem is backcountry skiing. They are sort of heavy, but the main thing is how hard it is to switch them into "tour mode" where you remove the pivots. They work much better this way, but if there's any ice, it can take 10 minutes of poking your bindings with a pointy object without gloves on.
