You'll wonder how you ever shopped without it – BuyOrNot - Scan Barcodes to See Product Ratings and Reviews / QR Code Reader Review

I do most of my shopping online for both the convenience and the ability to peruse user-reviews of the products I'm considering. When I do shop in a store, without access to user reviews, I'm like a fish out of water -- reluctant to make any big purchases without first browsing online to see what users have said about the item. Buy or Not solves this tricky problem brilliantly. Just scan the barcode of an item you're considering and you'll instantly see a list of all the rating scores (e.g. 4 stars out of 5) and the number of ratings for that item at several online stores. I tested it out this morning at Bed Bath and Beyond, where I was looking at a coffee maker. Buy or Not showed me that one of the items I was considering was rated an average of 4.5 stars by more than 450 reviewers.
