I love this polish. My manicurist uses it as the base when I do french tips or nail art where I want a natural-looking base. It is very light and very natural looking. These photos are two thin coats of satin slippers, and as you can see it looks like my natural nail. It's natural looking enough that when my nails grow or the polish inevitably starts to lift away, you can't tell just by looking at my nails. That's part of the reason I do this so often because it grows out prettier. :)
All that said, I love it for my use, and I knew when I bought my own bottle what to expect. But as others noted the photo is a bit deceiving because it looks more opaque. It's a great product as long as you know what to expect!
