Great invention, works pretty well. It does sting a lot when you put it on, and there is the possible potential to spread germs. What i try to do is not let the brush applicator touch the cut. To get it to stick, you have to put on more than one coat. It does smell like a bandage, but it really does keep out the dirt and germs and it stays on better than a bandage. It actually reminds me a bit of clear nail polish, using to seal your wounds.
