so far so good
I spent a little extra on these compared to basic BD I was looking at, I used them on one mixed climb and they performed flawlessly on ice, snow, slush and rock. I wear mens 11 Asolo mid weight hikers and they fit perfectly at the longest setting hole, any larger and you better consider an extended bar. The balling plates worked great (no need for tapping).
I love these so far and would recommend them to any other aspiring novice mediocre alpinist ;)
Update: To fit my plastic double boots, I refitted with Grivel Valter Long Bars. See product / reviews here at BC.
