Edit: I know how to use my locker, but it still won't engage. Update: I think it's the actuator

Yeah it's pretty good but no locker in the tricky stuff. I found it get me up a rutted out hill climb pretty good while the locker would just want to swing the back end out because the front is open.

 

You deserve credit for showing us what you can do without a locker.

Yeah, there are still occasions where I could have used the locker. But, I'm still very impressed. As you mentioned, It's very handy for climbing steep things.
