Used every day for 3 years now and still going strong.
The actuator never touches the microswitches themselves but rather some metal arms. It’s got a good sturdy restrictor plate that can take a beating. These thnigs are bulletproof. A little difficult to do the old quarter circle with, but they are nearly indestructable.
