So, I got some gratis from work on tuesday, YES it was GoSmile's B1!
GOD am I excited for it to start working. Though it was hard to capture it on camera, these pictures are my before in two different lights. When you take a look at the side teeth, compared to the front, I do have some yellow discoloration (occasional smoking and coffee drinking and a whole HECK of a lot of red wine).
This was two days ago, and concentrating the application on the worst discoloration, I have started to notice a tad bit less of a contrast. Once I've actually used up the whole set I off course will do the before and after.
BUT I AM SO EXCITTTEEEDDDD!!!!
