I purchased this item because of the review by real2all1. His review is correct, except it takes 3 AA batteries. Here are some helpful hints that I also learned: 1. This device destroys night vision in the eye that you are using. However, there is a cure. Put a red lens over the eyepiece. I used a red lens that came with an old AA flashlight that I had. The lens has a diameter of 1.120 inches, but a little larger would be better, say maybe 30-35 mm. I held it in place with small pieces of Scotch Tape. 2. After turning the viewer on, the first thing you should do is turn the eyepiece to make the display (battery, sensitivity level, and IR level) come into focus. Later, when you are looking at objects, turn the objective lens, similar to the same way you focus binoculars. 3. Give the item a fair chance to work properly, as you learn how to use it best I suggest looking down a dark country road with no houses around. Focus the objective lens on the fence posts and trees along side the road. ( I could easily see over 100 yards). Walk down the road 100 yards, then look back at your parked vehicle, that has headlights off. See how clearly you can see it, as well as a person if someone is with you. 4. Settings - I found that the medium, frame rate setting of 15 worked best, in conjunction the medium and high IR settings. Changing the magnification from 3X to 6X was worthless. Zero magnification (1X) would be best. 5. Uses-The viewer works best in open country. Looking towards vegetation that is only 10 to 20 yards away causes an overload of reflected IR light for the viewer. Use the default (low) settings, for both frame rate and IR intensity for best results when looking at objects near to you. 6. Finally, If I could have the manufacturer change something, it would be to add an interchangeable red lens for the eyepiece, and have only 1X magnification. Like reviewer real2all1, I think this is a fine unit considering a price of about $112.
