Got this for Christmas. Quite roomy, enough to carry work clothes. Haven't tried fitting a helmet or riding boots but will eventually. Attachment is by bungy cords (4) on each side of the bike to the passenger pegs and wherever else it suits you. Overall quality and ease of use is great.

Got one problem though. The bag rides up to my rear on my '05 Kawi ZX-6R/636. There's no passenger grab-on and with the undertail exhaust and a fender eliminator, I'm not sure I have any other options for preventing this but am open to suggestion.

Mine does the same thing. I have pegs for luggage on the tail that I use to wrap the bungees around. One time I crossed them side to side, which tightened things up.

I usually carry my work laptop and clothes. Any hard braking and I get hit in the butt. Takes getting used to, but I brake straight up before hanging over for tight turns.

Still quite happy. Too small for a helmet I think, and I don't think i can get much more in terms of clothes. Someday i think I'll get the saddlebags too.

My new solution has been to use a bungee cord around the handle of the bag and between the bag and the pad. Then put the hooks of the bungee onto the rear of the passenger seat and it stays in place. I was initially concerned that it would pull up the passenger seat back but I have not had any problems and it doesn't matter how hard I brake, the bungee holds the bag in place.
