I'd say the biggest problem is JT's fault, trying to get the goggle strap out of the goggle. You don't need to be a sniper or anything. It helps everywhere. Put one of these on your mask and you will be unseen throughout the whole game. These are the ultimate camoflauge for your mask.
Nothing beats it.
This is a great present for the sniper. If you get some paint on it, it is hard to clean off. But after a few days, it just wears off. It was somewhat difficult the way they explained it to install. You just have to figure it out yourself.
