Youn have just got to be more carefull with your hardware! 
It's not me that needs to be carefull, I have two little boys aged 3 & 4, was they that broke off the caps. My p55 usb3 did not survive after my boys used it as a trampoline

so I got the p55a ud3 to replace it

Will be moving my hardware to the spare room one day soon.
