I have Aquanots both front and back and would have to say they are just OK for the money. The attachment system leaves a lot to be desired especially when compared to Ortlieb. My big gripe is you have to replace the hooks if you are using oversized tubing like Tubus etc... whereas Ortlieb provides spacers. Hence, they aren't that interchangeable if you have bikess with different types of racks or even the same bike w/ a Blackburn lowrider in front or a Tubus in the rear which I had. Having said that, once the panniers are mounted, they are solid and the material is durable. But for the same price, you can get Ortilebs.
