bad quality
This product, in my opinion is bad quality. the zipper has already busted after a few mild rides. For that one reason i'm giving this 2 stars. other than that it is great, but without a zipper, i can't use it.

Perfect
I was looking for a nice little bag to fit under the seat of my wife's bike so that she could carry misc. items like keys, money and camera. This bag works great, and it even has a little loop to hold the rear flashing light.

Not bad
I keep the essentials in here... I always have a psi gauge, my 10 function tool, my headlight (a big 4 battery LED), a can of tire sealant, and some tire patches. Depending on my ride I usually also put in my cellphone and keys. it gets kinda tight with more than that stuff in there, but I have been able to throw in a pocketknife and my drivers license in there with the other things. I'm thinking of investing in a rack and a bag, but this will suffice for now. When I need more things like work clothes, or school books, I usually just wear a backpack. This is a nice little bag, and several dollars cheaper on Amazon than I've seen elsewhere.

Flawed design, but fixable
The size is what it is. Some seem to think that there are some magic bags out there that are actually bigger on the inside than other bags the same size. Sorry. Aside from that it is a good price. But, the top velcro straps will not hold on long, especially if you are doing any off road. It came lose 3 times on a 30 mile flat gravel trail. The position of the straps also makes it nearly impossible to get it tight under the seat. In a tightly strapped position, you cannot get your fingers in there to secure it. That is why most bags have one strap that goes through rails under the seat and wraps around and under the bag. If your stuck with this bag, you can use a plastic zip tie to secure it better. It won't come off and go back on without cutting, but at least it will hold. I would recommend a single strap pack though.

I regret buying this bag. Please observe the bag image and read my review.
Take a good look at the photo of the bag. See the strap on the top? That double end Velcro strap is suppose to fasten to the bars on the bottom of your bike seat, but it does a horrible job of doing that. Imagine pinching a piece of fabric with two fingers and trying to pull it between an inch wide gap as far as you can, and then imagine trying to be able to get that strap to touch another strap that is exposed through a half inch gap. Strapping on this bag is just that difficult. If you already have your bike seat on your bike like I do, you will have a difficult time fastening the Velcro straps [the straps on top] to the bars on the seat. Pulling off the Velcro is not a problem, but tightening the strap is a huge challenge. I am 5' 6" and I have my bike seat fairly low, so in order to have the bag high enough so that it's not dragging and touching the top of the rear tire, I have to make those Velcro straps as tight as possible. Whoever designed these bags didn't account for the fact that people need these bags fastened tight on their seats - when you get the Velcro on tight; there isn't enough "furry" to "scratchy" Velcro surface area to keep it fastened. The Velcro is hard to adjust because you have to pull the furry ends off the bag and reseal the straps through the bike seat [which have really tight openings and its extremely painful on your fingers trying to refasten the straps from under the seat. Even though I was able to get the bag one, it was still loose and the bag was dragging on the tire for a good 20 miles and when I got off my bike, I found an inch wide hole burned on the edge of the bag because of the heat from the friction with the tire. This strap has a horrible design flaw for a component that is critical in keeping the bag away from other moving parts.
