Query: good quality for price

This bag has been very durable. I don't use it every day. Just on days between going to the gym. It gets use 2-3 days per week. The only problem I had was that it was pretty hard in a few areas. I went to a sporting goods store and they had one hanging up and it was much softer. The guy told me (off the record) that they had went against manufacturer's recommendations and unzipped the top and removed some of the filler. I did the same at home with mine and then rolled it around the floor to more evenly distribute the filler and it is much better now.
