The product is absolutely WORTHLESS. I used it for four weeks, at least four times a day, and NOTHING about my nails changed.
Not only that, but the company BLOCKS negative reviews on their FB page and on their ads. I posted a negative review ONCE, and forevermore cannot post anything on their page.
This company is a disgrace. Check out their website. Buried in it, they have a statement that essentially says "don't expect this product to actually work."
Stay away. Far away. Their products are expensive snake oil. I don't believe that ANY of their positive reviews are real. In fact, there's another websit that says the positive reviews on Amazon are suspicious.
