Lurker, here.
I bought mine from buy.com as well. Got some industrial velcro at Joanns. For best adhesion, cut a space out for the little 'feet' and then lay a strip on top of the feet as well. I only needed to do this on the front (cupholder facing forward) as the rear feet are flush when velcroed around them.
I slid it forward enough that the extra cupholder and the well can still be used, this way the end of the cooler is flush with the edge and you can still use the rear cupholder and well area.
The door holding the cord is a piece of crap, already snapped that off, so be careful.
I have to disagree with the 'plenty of room' for the ER brake. You can use the brake but you have to sort of do it underhanded, in other words you can't wrap your fingers around it because there's no clearance between the brake and the cooler. It is functional, just funky.
The cup holders look dinky but they held my McDonald's Sweet Tea which was the critical pass test.
You have to push the blue button to lock as well as open the cooler lid. But for $20 with free shipping I can live with that. There is a ton of space. Great for dog treats, etc. These coolers usually work best with pre chilled stuff, so for me, I don't think I'll be using it very often as I don't travel that far on a regular basis.
Hope that helps. It's worth it to take the time to cut the velcro to fit and compensate for the uneven bits. You know, if you are like me and will insist on sitting there for fifteen minutes seeing how much it moves after installation.
