I haven't personally even laid my hands on one, however a friend installed one on his 06' Tribute and swears it is the greatest thing since sliced bread. The idea of having the square hard lines makes sense if you think about it. If you are applying any torque what so ever you will feel that square edge and make you think twice about what is going on. I'm thinking about one for my 05' allegiance, but I want to try his first.
