FirstGear Onyx Saddlebag?

Just wondering if anyone has the FirstGear Onyx expandable saddle bags and what your opinions are?
I am looking for a larger soft luggage option and these seem to be a decent size. Any thoughts on quality, durability, or the mounting system?

Thanks

Wow...those look sweet.

 

Well I read some reviews online and most thought they were nice bags so I but the bullet and ordered them. Coming from a BMW with side cases to a VFR with no storage space I really couldn't wait any longer. I actually rode my new bike to the store to pick up groceries yesterday not realizing I had no way of getting them home.
When they come in I will post pictures and a review
