Bests & Worsts Reviews from Amazon

I have been buying this product for several months now, I go through a lot of it, and have used several bottles. I LOVE J. Crow's Lugol's it is helping me in so many ways. BUT, from this particular seller, I received a diluted bottle. after using it for about a week... I could tell it wasn't working the same - and I felt it looked lighter than normal, but the bottle was sealed so I didn't think too much of it, after 2 weeks, I new it was not the same product. I have since ordered a new bottle from a different seller, and it is fine; a much darker color, and after a few days I can tell the difference.
