These Caldwell bags are simple and effective. You could spend a lot more money and/or do a lot worse than these. I've read some reviews complaining that the bags come apart at the seams, which seems possible as the bags come over-filled to the point where they are almost bursting apart. What I did was just let out some of the filler so that the bag had more give and sat better in the rest. If you're just using the bag for the purpose it was designed for-range/bench use-then I don't see durability being too much of an issue. The gun stock sits in the bag, it should slide back and forth, and that's it. there is no need to touch the bag very much or throw it around like a bean bag. It should last, and so far I'm pleased with it.
Pros: affordable, easy to use, well-shaped
Cons: potential durability concerns
