Stealth NATO Strap
I have got 2 stealth NATO straps coz it's cool looking (all black, including metal parts). However after using for 2 days, I find most of the black coating on the metal portions disintegrating into fine powder. I feel the black coating is very soft and a slight knock will cause it to disintegrate. I've tried to "patch up" the portions with permanent black marker whenever I can. Photo :

Hopefully the future batches of stealth straps will have overcome this issue ....
