This is a very high quality projector. I took a chance on the dangbei atom as I was looking for something for my home theater and I was also very curious about having 3D in my home as well as I thought that would be fun for me and my friends to enjoy. I can say that the dangbei atom is 100% worth the money. Just keep in mind of 1 thing before you buy this projector and that is it is a 1080P projector. 1080P looks great on smaller screens up to 120 inches. After 120 inches you will start to lose brightness and you'll start to loose pixel density. Things will also start to look blurry in perticular smal objects and items on screen will be blurry until more pixels can get to them making them appear clear. If you notice some blur you can wipe the lens with a lens cleaner like you use for glasses but you may still see this. It's not the projectors fault this is happening but the laser technology and quality helps keep it to a minimum for large screens so if you can't afford 4K I would say this is the BEST value for the money. The 3D is amazing but I must tell you that in order for you to be able to make it work the image MUST be set to default keystone no change must be made even with the zoom do not change it. 3D Bluray will give you the best effect possible and you will need a 3D bluray player to accomplish this. If you don't plan to be watching 3D constantly day to day I would buy a used one on ebay that is working well. I got an LG one for 25 dollars and had to buy the replacement remote but it was not that expensive so I went ahead and did that and it worked fine. This projector will not stream any video you want it doesn't support 3D properly for any content you stream on a stick or on google TV that isn't rendered for side by side viewing or top and bottom viewing. in the 3D mode the SBS and TAB options other than Bluray 3D are only going to work is a video is rendered for 3D so the projector can merge the 2 side by side images for each eye making the 3D effect. That is how u get those effects to work. As far as the 3D Glasses goes just charge them up and press the button on the top of the glasses to turn them on. Make sure the room is dark as light will make it hard for the glasses to do their job. I am not sure why this is but the way they work light probably confuses the glasses on what to visually work on.. Overall for the money this is a great value and I think you should consider it if you're on a budget and want something of high quality. The build quality on the unit is really nice too so that is also another plus. This will work well for screens up to 180 inches but just remember anything past 120 inches is not the projectors fault that's just 1080P so if you don't want any blurriness or pixel density issues go for a 4K projector. But as far as 1080P projectors go for handling images of large scale like 180 Inches which is what I have. This works pretty well! Better pixel density than competitors.

This is the best projector that I have ever had. The automatic focus feature is neat. The images are bright and clear and saturated and in focus across the entire screen for both text and movies. There is no laser speckle. I could do work on the projected screen as an external monitor. I recommend getting a camera tripod that is about 3 feet or 1 meter high. You might also want to buy a projector screen if you do not have one, because a projector screen is not included. I purchased the Dangbei Atom projector and Dangbei 3D glasses combination. The package includes 2 AAA batteries that you have to put in the remote control by sliding down the back of the remote control about 3 millimeters and then pulling the back of the remote control off to reveal the battery compartment. The 3D movie viewing experience, once you get it working, is better than using the PlayStation VR headset on the PlayStation 4. Unlike the PlayStation VR headset, there are no screen door video artifacts when you view 3D images projected by the Dangbei Atom projector. That PlayStation VR headset is heavy and squeezes my head like a vise while the Dangbei 3D glasses are comfortable and light and feel like a pair of sunglasses. The only downside is the totally unintuitive multi-step process for viewing 3D videos or movies. You have to first charge your 3D glasses by plugging the small end of the USB cable under the nose piece and plugging the bigger end into a powered USB A port in a computer, a powered USB hub, or a USB AC adapter. The light in the white button on the 3D glasses will be red at first and will eventually go off when it is fully charged. After the glasses are charged, you press the white button on the glasses once to turn it on. You hold down the button for 3 seconds or so to make the button blink 3 times and turn the 3D glasses off. The glasses also seem to turn off automatically if they do not see a 3D image for a while. You have to hold down the Home (white house) button on the right side of the remote control, navigate to Projector / Image Correction / Reset to Default Image. You can then press the white left arrow button until you exit the menus. I don't understand why the user has to do this. This should be done automatically for the user any time they attempt to activate the 3D setting. You make selections by pressing the center depression of the circular control on the remote control that lets you move up, down, left, or right in the menu. Dangbei also recommends holding down the Home button, selecting the cog symbol to enter the settings menu, selecting Projector / Focus / Advanced / Auto Focus When Moving. This will turn off Auto Focus When Moving. The selection is off when it is white to the left instead of blue to the right. The presence of the 3D mode option in the Home / Picture menu gave me the incorrect impression that I had to set 3D mode first before viewing a 3D video or movie. I was wondering why the 3D mode setting selection that I made in the menu never worked and kept changing back to Off. Instead, what you have to do is start to view the 3D video or movie first. When you see double images side by side or one image on top of another, you have to hold down the Home button that has a white house symbol on the button. That will then reveal a menu on the right side of the screen where you can select the Picture menu option and scroll almost all the way down to select the 3D mode. There are 3 options for turning on 3D mode where the images are on top of each other, side to side, or coming from a Blu-Ray player (such as a PlayStation 4 connected to the projector via an HDMI cable). After changing the 3D mode, you have to press twice the button that has the white arrow pointing to the left on the remote control. The Dangbei video on YouTube does not seem to show this last part, which is necessary or your 3D mode selection will return to Off. The PlayStation 4 requires some changes on the PlayStation 4's menu on the far right side for Settings / Sound and Screen / Video Output Settings / TV Size to specify the size of the projected screen. If you are off by 1 inch, the 3D image might not look right, as if you were crossing your eyes. For some scenes, I have to select 80 inches, and for other scenes, I have to select 81 inches. When you go back to viewing the video or movie after selecting the screen size, the 3D mode will be Off again, so you have to go through the process of holding down the Home button on the remote control, going into Picture, and selecting the 3D mode again after each try of adjusting the screen size in the PlayStation 4 settings. That is a really tedious and time-consuming process of trial and error. The reward is a clear 3D image.
