I've had these tweezers for about 3 years now and it's still the same quality as when I bought it. I love it because the head is slanted and easily grips the hairs ( even fine, short ones) because of the diamond dust coating. The reason I give it 4 stars ( I'd give it 4.9 if I could) is because I know it does not cost that much to coat a small edge of a tweezer with diamond dust. I use professional nail files with the same coating for $20, so in comparison it is expensive, but still worth the buy!
