I have used the bar quite a bit not only for technique, but also warm-up and metcons where I want to set up a 45 pound bar (15 pound bar and 15 pound bumper plates).
Over the past 6 years, the bar has held up great. The finish is in good shape and I have never been worried about damaging it. I don't drop it from overhead and have never loaded it over 55 pounds.
I definitely like having the bar in the gym for myself and my wife and kids if they ever want to join me for a workout.
