im pretty much thinking the same. half the time it doesn't return any result and the only time it works well is on a well known logo - like Coca-Cola. i've tried QR codes & regular barcodes with it & got nothing.
To be honest I can't stand Goggles. It rarely ever finds anything I scan but Googles Shopper App works perfectly for scanning barcodes. I predict Goggles becoming a scrapped project within the next 18 months.
