This is a huge confidence builder for me and my thinning hair, it just takes a little practice.
I purchased the light brown.  I color my hair with warm tones and highlights, and it worked for me.  It is a bit on the warmer side as others have noted.  As with the other items I've gotten from this brand, the colors are very consistent and work for me.  I use this to create fullness with my existing thinning bangs.  It takes a bit of time and practice to learn how to style it and hide the full clip end in my bangs without it looking obvious (it's much fuller than my actual hair...especially comparing the small clip area to my normal scalp). I've also learned to blow dry it out to create a small amount of volume at the clip instead of it lying completely flat.  If I part my hair appropriately and place the bangs a bit further back than you might expect, it looks really natural.  I did cut the side pieces to be the same length as the bangs for a bit more width. I have added slight highlights to my pieces from this seller, and that has helped me match my own hair even better.  Next I will be adding slightly darker roots to the pieces...more like lowlights, so that as my color grows out, it won't be so obvious that the lighter roots of the piece stick out.  All in all, totally worth the money for me.  My thin bangs are only getting thinner as I age, and this makes me feel more confident and less self-conscious.  I will buy these again.  For the price, getting a new one a couple times of year is totally worth it for me.  I do wish it had two clips instead of one.  It stays firmly attached without issue, but while styling, it often shifts a bit, like a pendulum because it only clips on a single point.  It is a minor issue, but one I would definitely pay extra for.
