This kits is worth the money for sure! It's nearly invisible once everything is on the bike, and it is really sturdy!
My only complaint, and it's minor, but legit:
The kit comes with 8mm bolts and 10 mm bolts. The 10mm bolts did NOT come with nuts, but the 8mm bolts did. Of course, I needed the 10mm bolts. A quick trip to Lowes for some bolts and I ended up getting grade 5 bolts and nuts any way :)
I also bought a few extra washers as the kit only had enough to place on the inside of the bag and I preferred to have them on the outside as well. No lock washers were included in the kit.
Bottom line: for the $$$ you can't beat this kit!
