Free is free, and this was one tiny bottle, at only 0.16 fluid ounces compared to others which are normally around 0.5 fluid ounces. Even the China Glaze Matte Magic was 0.325 fluid ounces. Here's my bottle next to a bottle of Seche Vite top coat.
Glamour Do is a very sheer, very light pink. It took me 5 coats to get this level of opacity, and as you can see, I smeared my pointer finger. By the time I was done taking pictures, I smeared my ring ringer too, hah. Overall it's a pretty color, but I'd probably use it either as a layer color over white, or just as a quick sheer for the day.
