My initial impression is that these are pretty amazing for the price, and for a low light CMOS. They're not Gen 3+ IITs, but they aren't a cheap video camera without an IR filter, either. Yes, they're a somewhat unknown brand, but the reviews you see on Youtube aren't fake. The low light performance, even in full color "daylight" mode, is amazing. I haven't tested these way out in the country on a moonless, overcast night yet, but in a semi-rural area, I can absolutely see people and animals from hundreds of yards away. I can read license plates in the daytime from over 100 yards, and close to that distance at night depending on the lighting conditions. With the (allegedly) upcoming 70 and 100mm lenses, I assume the optical magnification will be over 10X (with a 4K sensor), which is a lot. The modularity of this system is really great, with swapable lenses and the ability to add the rangefinder unit later. It would be really cool if OneLeaf makes it easy for third parties to make additional accessories, as well. It's a great core platform for that.I haven't tested the video recording capabilities. The display screen on the device definitely isn't 4K resolution, so the pictures and videos you take should look much better on a big display than they do in real time. I can't say for certain, though.One odd thing: the laser component for the rangefinder is built into the core unit. It's also not an IR laser. It's a very bright red laser. There's no way you'll be able to prevent people from seeing that you're using it even if they don't have a night vision device.Not everything is amazing. Like all the widescreen form factor binoculars, there isn't a diopter adjustment like there is with IITs. You're essentially staring at a cell phone display. You'll need your reading glasses. I don't think most people could put the device right up to their eyes, whether they need reading glasses or not. These aren't tactical binocs for moving around in the woods at night, though. They're for looking out your window, or from your car, where light discipline isn't that critical. Holding it 8-12 inches away from your eyes is sufficient.While there is a manual ISO setting, the options don't seem to encompass the entire range of the camera's capability. ISO 3200 is the fastest manual setting, but switching from ISO 3200 to "auto" ISO seems to unlock much faster shutter speeds. The inability to manually cycle through the full capability of the camera makes looking at objects with backlighting somewhat difficult. The "auto" mode adapts very quickly, though, and as long as the scene doesn't have dramatic variations in brightness, the camera will pick an ISO that allows you to see everything well. There's also an "exposure" (EV) setting that allows some additional manual control, along with a light-limiting partial lens cap for use during the day or to reduce glare in brightly lit scenes at night.One big issue is that the menu options aren't organized very well, nor are there hardware buttons assigned to what I assume would be the most useful controls: ISO and EV. Changing the exposure and ISO values requires multiple clicks through on-screen menus. The buttons are positioned well next to the handles, so after a little practice, you can do it without moving your hands or taking your eye off your target to look at the buttons. It would still be nice to have hardware buttons for ISO and EV, though, or maybe have user-assignable button maps.Overall, I think even people who are very familiar with IITs will find this device pretty insane. It seems to be comparable in low light performance to the Sionyx devices, though I haven't compared them side by side. OneLeaf also makes a 1X magnification monocular that is possibly the same sensor as these binoculars, and which does appear designed to be used to be able to move around, but I haven't bought it yet, mainly because it's not sold on Amazon (same reason I didn't buy the Owler1 from WildGuarder...you never really know if "free returns" means you have to ship it back to China....). If it has the same capabilities as the Find, though, it's an incredible value. Unlike most people interested in night vision, my use case is defensive, not offensive/hunting. A CMOS device is much more adaptable to sudden bright lights, and is much more amenable to being kept by your bedside, with 18650 battery inserted, than an IIT.

I cannot say enough great things about this. The day images are very good but where it excels is the night.

REMEMBER TO REMOVE YOUR BATTERY PROTECTION TAB BEFORE RETURNING.We use this sometimes to see any animals out in the field across our house between my neighbor and mine. Sometimes makes for a fun spooky little night. The recording feature is great. Huge plus for replaceable batteries. They're 18650s enabling this thing to work for many years to come. I haven't watched any of the playback yet on the videos but the screen resolution is pretty nice. Very clear during the day. As for the image quality at night - just remember that this is not true NV. This is IR NV which from a long distance, you need some sort of light source to make out what you're looking at. At full zoom, it can be tricky to spot your object but the 3/8th mount on the base is nice to put it on a tripod instead of holding it for long periods of time. Great packaging and support. I would recommend it for someone who thinks they want NV but in reality uses it once a month or so.

NO clear instructions. Must have some basic experience before buying

I was hoping that this would give me a better view of wildlife that I get with my camera and telephoto lens. It does not. One problem I have is that the images are on a screen. Since I have presbyopia, even in-focus images are a little fuzzy to me. I can overcome this by using my reading glasses. However, even then there are issues. In the least zoomed mode the pictures are pretty clear as seen above where I show the birdhouse on the tower. However, when I zoom in, the image is not that clear as shown by the closeup of the birdhouse. Part of this might be my ability to focus since it is a manual focus device, but I am generally pretty good at finding the optimum focus even when it is not totally clear to me. The other minor quibble I have is when one takes a photograph, as opposed to a video, there is no clear indicator that the photo was taken, no sound or onscreen message.Of course, there is one feature of these binoculars that the average pair does not have. They allow you to see in the dark. They definitely allow you to see many things in the dark better than with one's bare eyes. Unfortunately, the clarity is about the same as with daylight viewing which I wasn't really happy with.

For my first time getting into night vision gear, I am very happy with what I received for the money I spent. I can 100% say that I am very impressed by what these can do. If you are expecting to see things just as you would in the daytime from 200 yards away, then you have unrealistic expectations. My experience has been using these when ice fishing and needing to check my tip up flags in the middle of the night. I don't want to shine a flashlight and let everyone know where I have my fishing spots. So I am using this to view my tip-ups. I can see clear as day 150 feet away on a lake with snow using these goggles.I am very happy with them.
