Ok...if you're thinking about spending dollars of money on this,then I have a better suggestion for you. Go to Radio Shack and buy the most expensive sound system available. Then find the deafest guy your wandering eyes can spot and give this newly-purchased sound system to that person as a gift. Doing this will render your squandering of finances to be at least a charitable ordeal,and you'll get a tax-break as well....assuming that you're into that consolation stuff. In a less poetic version- this hub guard will annihilate your axle with its "ingenious" grub screw design and ultimately force you to buy a new axle or a new hub- you make the choice. You can't say I didn't warn you in a beat-around-the-metaphorical bush sort of way. 1 star is generous.
