I have a slightly cheaper version of the Allen rack; the difference being yours has better gripping tie-down straps while mine has straps made of slippery nylon webbing that quickly become loose within their buckles. My solution to fix that problem is to tighten the straps and then secure them by wrapping them tightly with a bungee cord. Of course this means I have to take care not to scratch my bike. And of course I am paranoid the bungee might break or come off so I keep an eye on it while I am driving. But for the few times a year I use the rack, it is mostly OK otherwise.
