That has lasted very well. I don't tend to run with any sort of bag. I just tend to have my phone and keys with me, but I don't run to work as it's a bit too far. I may look for something as my arm pouch is not too comfortable. There are waist pouches that may do for my needs.
I do have a bigger backpack that I bought many years ago on a work trip to the USA. I am still using that one. Some things do last.
