ProsourceFit Multi-Grip Chin-Up/Pull-Up Bar

I've been using a pull-up bar for a while now, and while it has some good points, overall, I'm a bit disappointed with it. The pull-up bar itself is pretty solid and was easy to install. It fits snugly in the doorway and feels secure when I'm doing my exercises. The grips are comfortable, and it allows me to do a variety of workouts without any issues. However, there's one major downside that I can't overlook. Over time, I've noticed that the pull-up bar leaves a black mark on the door header. This mark is quite noticeable and really detracts from the look of the door. No matter how much I clean, the mark just won't go away, which is pretty frustrating. While the pull-up bar does its job well, the issue with the black mark is a big letdown. Because of this, I'm giving it three stars. It could be a fantastic product if the manufacturer could fix this problem.
