Cab is right, a locker can be a clunky, shifty thing especially when cornering at low speed. That being said though, if you can tolerate the manners of them you might like them like I did mine. I had one in one of my Trans Ams with a manual and healthy LS and 35 spline Currie 9". I ran 28x10 bias plys on the street and on the track with that car and the Detroit Locker was dead reliable. But trying and find one to ride/drive in first is good advice, they're not for everyone.
