The Good: They really grab your shoes
The Bad: they destroy your shoes
I´m using this pedal about 1 year and they keep working normally. I've never had to replace any bearings. The axle are strong but a had to straighten a few times when I hit the pedal on the floor.
The bad about this pedal are the pins because they destroy your shoes quickly. But the pins are removables and you can adjust as your necessity.
