“I have enjoyed using the dumbbell holders. However, there are several design flaws. (1) The retaining clip is located at the bottom rather than the top of the holder. Because of this, the holder is more than an inch away from the rack at the top, It should fit snuggly at the top. (2) No matter how I position myself on the bench, the dumbbells will frequently clip the corner of the holder and make lifting more difficult.
