I'm a Japanese man. Because I have thin arms, NATO straps tend to leave too much excess material. This buckle helped me to achieve a more balanced look. However, the metal parts would often pinch the skin on the inside of my wrist, causing some minor damage. I've gotten used to it now and it doesn't hurt anymore. I think it would look better if the buckle was a little smaller. Despite all that, I love it! I can't let it go!
