These came recommended to me after I complained that no matter how much I tried, I ALWAYS smudged my nail polish while waiting for my nails to dry.
I purchased this and definitely would recommend. Since you only need about 1-2 drops per nail, this bottle will last you a long time and be worth the cost.
You just release a drop or two on each nail after adding your top coat and then your nails are almost instantly gone.
It make my cuticles a little greasy but maybe it's moisturizing them.
