What do you think of these night vision goggles?

Are they good enough to just see through the night or is it too much of a toy?

It is gods gift if its a proper night vision goggles or if you know how to use it. But its a toy in the hands of a inexperienced fellow.

Well based on the price and what I read when I looked them up on another site they look like they won’t "see through the night" any better than a camera with ‘night shot’ mode. I’ve tried a few such cameras and they seem to be able to see very minimally in the near infrared, and not to very far away. Good vision is only available with the aid of an infrared light. Then the limit of your vision is how far your infrared light reaches. About weak flashlight distance, maybe two to ten meters (6 to 30 feet) depending on the light source.
An infrared light will not be visible to the naked eye but will be very bright to anyone with equal or better night vision equipment. So if you’re using them for stealth this is not the product for you.
Good quality night vision goggles can allow you to see with no infrared light to 25 meters or more, with no external light source.
If your interest is just still photography you can get a 35mm camera, put an IR filter on it, mount it on a tripod, and take long exposure shots. You can see to a good distance with this, but it won’t be good for viewing anything that is moving, due to the exposure times required. Also, depending on the amount of ambient light, you may do better with just visible light and a long exposure (without the IR filter). Make sure the camera you are using does not have a mirror or lens coating that absorbs IR, some of them do.

Personal experience. I’ve used military NVGs, PVS14 mainly, but also 7, and done infrared photography like I describe above. Have tried out ‘night shot’ mode on several still and movie cameras and find it’s only really good with the IR flashlight on.
