Decent bag, won't stay closed on rough

I've put it through the wringer

The bag seems well made and is pretty water resistant. The magnet is strong and does a fine job on pavement but have had it pop open multiple times on gravel descents, one time losing my phone. Other mag lock backs have notches/teeth that I've wondered about, now I get it...they keep the bag from flapping open when your phone or cargo bounce up against the top. Probably fine with light things like gel pouches, maybe even energy bars. But...I'm returning it.
