I can't really tell if this works any better than vinegar - or water, for that matter - but I do like how easy it is to clean with (as long as you maintain your glass properly and not sure it once every "whenever I feel like it"). The smell isn't too bad, the spray works well all the way through the entire bottle, and with the colour it's easy to tell where you've sprayed. I'll still continue to buy it, but I wouldn't be beyond cleaning it with other things - especially since a "disinfected" mirror doesn't really matter to me since its purpose isn't to be touched.
