I like that it’s easy enough so even someone who doesn't know much about computers could figure everything they need in order get going with guard grabbers right away! There are some things we haven have figured our self but if you're asking questions there shouldnt really anything else your missing when using this service!! So far nothing at all because its great. We've made several contacts already which makes me happy :). I like that it helps me not having my car broken into while i am at work in Manhattan; but also being able help other people with similar situations! There are some things about this program which don't make sense so if you have any questions just ask someone who works there because they'll know what your talking abouut anyways :). That its helped alot of peoples safety when going places outside NYC especially after hours (not during business day).
