The clips last a very long time, if they are somewhere they won't get bumped or snagged, and don't bear the full brunt of the weight of the Maglite. I kept a 3-cell mounted in a vertical position in the rear corner of my standard cab pickup, Maglite butt on the floor. Over 20yrs. It was easy to reach there, but protected.
The problem isn't their weight-bearing capabilities, its the fact that when you clip the light in and out, the prongs break after a couple of months of use.
If you don't really use the light much, then I guess you're ok with it. If not, get Quick Fists.
