I had the original (overpriced) Waller and Sons range bag, but one of the Fastex buckles broke after about five years and then the "self-repairing" nylon zipper broke just a month ago, so that the bag falls right open (!) while being carried. The bag is only six years old, gets weekly use, carries 1-4 guns at a time, maybe 2-5 boxes of .45ACP ammo plus glasses, hearing protection, hat, etc, and hasn't been abused, so I'm not very satisfied with Waller quality.
I replaced it with a bigger "Tournament" I-Shot bag for half the price.
