Query: This bag sucks

This is a beautiful bag in all ways but one. Unfortunately, the one way renders any positive features obsolete. THE MAGNETS SUCK! The magnets are so weak that the bag barely adheres to the tank. I have been riding with tank bags for twenty years and I've never experienced anything like this. A hundred bucks for a useless tank bag. What a sham.
