Review on ROCKBROS Resistant Bicycle Mountain Accessories by Adam Taylor

The construction is very good, not as complicated as it seems but more than adequate. It has multiple compartments that allow you to separate things, which is nice. Like many others, it is attached to the bike with Velcro fasteners. This allows you to move in one direction or another from time to time. I took it off the bike, added some tape and it seems to be holding up better. It's still worth the money and does what it's advertised to do. I would recommend.
