I have a new refractometer for sale. I received two as gifts and don't need both. It seems to be made of both plastic and metal but still feels rather hefty. If anyone is interested in getting rid of your hydrometer and start using a refractometer this would be perfect for you. I have used mine for 2 brews so far and it's great. I was able to check the gravity frequently and not lose a lot of wort. I can get a pic of it if people want to see it. i just don't have my camera at the moment.
