Quality concerns
Ordered blue blocker in October 2020 and the pills were a yellow color. The blue blocker pills I received in April 2021 are a purple color. After many emails eyetamins could not explain the color change. I opted to return the unopened bottles and was promised a prompt refund upon receipt of the return. I had to reach out and inquire about my refund 2 1/2 weeks after they received my return. Since they wouldn't refund me on the opened bottle, I had to pay for a bottle I will not use. So the guarantee really isn't a guarantee. I will not not be doing business with eyetamins ever again.
