I have had a few of these bags now as they only tend to last me a year. I play between 80 and 100 gigs a year and my gear does get thrown around a bit. After maybe 8 or 9 months, holes start to appear in the end of this bag and before long, the stands start to shoot out of the end when I'm lugging my gear in and out of venues.
I keep buying the same bag as it's cheap and practical. I see this in the same way as I see my strings. If you?re anything like me, it's something you'll have to replace eventually.
This isn't supposed to be a negative so much as a heads up. Don't expect it to last 20 years :)
