This Rack Bag is not bad for that price tag.
The pocket on the side is handy, and the grip on the handles is good.
I find the supplied screws not long enough so you can't host gear with a thick front plate, and the whole screwing system could be stronger.
That said, if it is for small trips and not too much wobbling around, it might just work for you.
If you can afford a little more, you can get a Gator rack bag, I owe one too and find the quality and attention to detail of Gator much better.
