I love, love, LOVE this product. I have been using it for over a year, and will continue to use it forever! My nails are much harder, and hardly ever break anymore, (even when doing extra tough jobs around the house, like finishing our basement!) I hope they never stop making it!! I will say, it does get very thick after just a short amount of time, (maybe a month or less), but I just use an eyedropper to add some acetone in and it's good as new. I only use one coat as a base, and usually let that dry for several hours or overnight before applying two coats of color. Sometimes I use it as a top coat, sometimes I don't.
