I bought these a few weeks ago randomly to try out and finally got them installed yesterday.
They work perfectly. I ended up only using 1, placed in a way that I can use the long strap included (they include 2 long, 2 short) and go across the middle of my quad.
Note that it does require poking holes in your backpack, but they are small screw-holes, and it's not as if you'll ever have to take this off once it's on a backpack.
My packpack was a little tough to work with because it's a Targus made of "puncture-proof" material. Hard to poke holes in material that resists holes...
Using these I went from having 3 elastic loops that kept me from opening the backpack with the quad on it, to a single strap that doesn't get in the way of anything.
If you have a backpack that doesn't have a good way to attach your quad on the outside, I highly recommend these.
Note: Mine came with blue straps, not green.
