My wife bought me a refractometer for Christmas a few years ago. I dont know where she bought it, but I'm pretty sure its this exact one. It looks pretty much the same as the photo. It works well, but I never really checked the gravity scale. Reading the reviews, it does looks like there may have been some bogus ones sold from somewhere. It looks like several places sell this one. and for ones that are not exactly whats listed, maybe amazon's listing didnt match what was actually being sold, which has happened to me twice in the past year from amazon. Both times the listings were wrong for what I ordered, Amazon was good at exchanging/refunding. As far as refractometers, I still use my hydrometer for most measuring. Maybe thats why I havent found it to be off.
