Not impressed [SEP] I was very excited to recieve this base coat.  I am attempting to grow my nails longer, now that I am getting older.  I would never purchase this product agaian. This base coat does not keep my polish on, and it creates not barrier for my darker polished. I put this on and then painted two top coats and my nails were still stained red from the polish.  I am very dissatisfied.
