Well, I can't say it's really good but at least you can see the target more brighter. But it's quite little.

And its monitor is very small, as you can see in my picture. It can show you up to 50~100m? distance in low visibility and its FOV is just 5'.
I bought this for costume play, but if I was a normal airsoft player, I would buy an 'affordable real working nvgs' such as Yukon.
