I've purchased night vision bino and mono's and most you can't look through a window without reflection or distortion, with this one you can. Another fantastic feature, you can view in daylight! Which is a great. Heck, daylight, nighttime, and in total darkness, through windows take a picture or video. A manual focus is a plus. Easy to hold, and lightweight. The battery life is kinda short but sufficient. If you were to improve on this item give us optical zoom in addition to digital extension. Overall I'd buy this monocular over again and have recommended it to coworkers.

I was some what tentative about purchasing a night vision scope as I didn't want one that was grainy and green like the old first gen nv scopes. I reaserched quite a bit before I biting the bullet and purchased this scope. I'll tell you now, I am NOT malcontent at all with the function of this night vision monocular scope.
The first thing I did after openning the box was put the scope on the charger, then set to reading the operations booklet. I let the battery charge for about 5 hours as I did a few other things, oh, I should mention the charging cable is only about 18 inches long.
After letting the battery charge fully I looked out the window and played with the focusing aspect and found that quite adequate. It was still daylight so I had to wait until nightfall before testing the night vision capabilities, I found I could see quite farther than I anticipated with the city lights and such. At that time I didn't know the infrared light wasn't on, I am suprised at the light capturing abilities of this scope. As I was testing the scope I watched a cat walk up the sidewalk about 350 meters away, just a plain as if it was daylight. I then took the scope out behind the house and was impressed with the picture quality in near total darkness, mind you, I still didn't know the ir wasn't on.
The next day I took the scope to work with me and showed it to a couple of co-workers, one of which was so excited at the way it lit up the viewing area that she said she wanted one, I sent her the link, both people agreed the scope picture was impressive and one even joked saying " this could bring in a whole new level to window peeking" ... smarty pants.

Now, after work I received an email message from ESSLNB, I work nights so the message arrived the next day while I was sleeping, it wad just a simple note saying thank you for purchising the nv monocular and it also contained some operational instructions that I think should be included in the manual. That is when I realized the ir light wasn't on! I was like "WOW, I was getting that kind of pucture WITHOUT the ir?...", that my freinds is what impressed me the most!
Now, once I learned how to adust the picture brightness, and adjust the ir intensity as well as turn it off I had to retest it all over again. Living in a metro area, its rather hard to find an area that is in total darkess but I was able to find an area that was close to it anyway. I found that there is alot of "splash" (for the lack of a better word) when using the infrared light. That is to say, when items a close and the ir light is high it creates glare ( splash) in the pucture. Turning down the ir intensity alleviates that but when you decrease the amount of ir light you also decrease the visable distance you can see.

All in all, its a good scope. Fits nice in the hand, has a wrist strap, tripod interface, can be mounted to a helmet or a rifle, memory chip, and soft rubber eye piece.

The only thing that I found wrong with the purchase is the instruction manual is lacking in operational instructions. Which the email I received cover quite well, thanks for that by the way.
Oh, I am worried about the battery. It is a 750MaH, 3.7v 14500 battery, I asked ESSLNB if I could order another so I would have a spare but they assured me I could find one locally.

Other than that...

Would I recomend this Nightvision Monocular?
Yes, yes I would!

First of all, this is a good camera for the price. no doubt. I have used it even in the daytime and it shows a good color image. at night, B&W image. I thought there was something wrong with it at first, because the eyepiece is just a tiny hole! not a lens. what? but it works. You just have to look right into the little hole. Image is there.

When focusing, my hand blocks the IR led illuminators. which is a strange thing to design. it throws the camera off completely. it takes a bit of time, then it adjusts again and you can see an image.

Night vision is VERY good.

Buttons are useless at night. You need a flashlight to shine on them to see, which then... you know... useless when you have to shine a flashlight on the nightvision camera and not be seen lol. why not backlight the buttons? how much can that cost? 30 cents?

The user interface of the buttons is horrid. also, when you press the left and right button, for example for magnification, you have to press and release. does not work when you hold the button. Magnification does not seem to be optical. it's digital. so at 5x you get only 20% of the resolution you have at 1x. hmph

runs on one AA 3.7v battery. the memory comes preinstalled. You need to READ the manual and work through the google translated English to understand what they intend to say. but its better than nothing.

Overall Pretty good night vision monocular.

Pros:
1) Pretty long range night vision not too difficult to figure out how to work the features.
2) CAN be powered up via a usb power bank (which greatly extends the run time before a recharge is needed).
3) Quality of captured photos/videos is pretty good day/night (if taken from a tripod).
4) It was very nice to see the included lens covers, power and video out cords/bag/and soft case for everything to store into.

Cons:
1) The included manual is pretty much useless (but at least gives you a rough idea on things).
2) Because the picatinny mount is right over the Tripod threads, a regular tripod mounting screw is TOO SHORT for it to work (not long enough to reach the thread). a 1/4" bolt cut to size WORKS fine however.
3) The time/date stamp displays in very tiny RED text at the bottom left of the screen and is very difficult to see it.
4) ALL the buttons are at the top and do NOT stick out much (if any at all). This makes using the monocular very very hard (if not impossible) to use at night in total darkness.

My Impression (and main reason I did not give this 5 stars

IF the buttons on the top stood out more (a little easier to find in the dark) I likely would have given it a higher rating. As it is My fingers do not have all the feeling in them (Diabetic).

nice price
