I bought my skis a few years ago used with demo bindings (Blizzard Magnum 8.1 Ti with Marker demos). The bindings seem to work fine...easy on and off, have only released the boot a few times during pretty aggressive falls, etc.
I basically dont notice the bindings at all because they are trouble free and work as they are supposed to.
I am looking at buying another pair of skis online and these will also come with demo binding (Marker Squire demos). I am not shopping for skis with demo bindings but it seems like every time a find a ski that I am interested in at a good price, they are equipped with demo bindings.
Whats the downside of demo bindings? The seem less expensive, they work fine, easy to adjust if a buddy wants to try my skis, etc. Is it that demo bindings are heavier, and if so, how much heavier (can you even notice the excess weight)?
