I've had my LW/PNT bag now for nearly 5 years, the only malfunction I have had is the foam handle cover tore-I fixed it with a handle cover(4 years ago) other then scratches, best damn bag I have EVER had!!!
If you get the LW/PNT bag, make sure you get a stabilizer strap!!! it makes a huge difference in keeping your flight kit from swinging.
