This is my 5th projector that I own so far and is definitely one of my favorite one!!! Out of the box, it looks super sleek and much different than the rest of my projectors, which are regular projector and this my first ultra short throw one that I have and I have to say that I fall in love with it right away. The projector's body is made of mix of aluminum and plastic, has a matte surface and looks very elegant with a shade of off-white/light gray color. Everything was smooth during setup and only took about 10 minutes to completely configured it and have it running. Here are some of the nice features that I really like:1) Automatic Key Tone correction: this feature works flawless and always able to correct the shape and size of the screen everytime the projector is moved, even just an inch off its current position, this feature would kicks in and re-adjust the image right away. Many projectors out there advertised this feature but rarely any of them would work as well as this one.2) The File Sharing option: which allow me to access any image or video or documents that are on the plugged in USB drive, it even load me install a stand alone APK file (An APK file contains all of a program's code, such as .dex files, resources, assets, certificates, and manifest file) and let me install it directly into the OS in case that APK is not available through the App store. It also has support for SAMBA share protocol, which is able to find all of my connected devices on my network and let me access them and load the image, video, music and document files. Not many projector out there offer this feature.3) Built-in Luna OS/Android App store: the user interface is very friendly, it has big icons and big text, making it easy to browse through the apps and options while sitting at 10 to 14 feet away. With the built-in App Store, I can find all of the popular streaming app like YouTube, YouTube Kid, Netflix, Spotify, Amazon Prime Video, etc... and install them with a single click. I watch alot of online streaming on my TV, thus this projectors serve my purpose very well by having all these streaming apps available. These apps run well and very responsive, I did not feel any lags or hiccups or crash during my usage.4) Built-in speakers are very loud, I normally only set it to about half bar and the sound can fill up the entire living room and it also have some stronger bass than all of my other projectors.5) Image quality is really good, even though it's only a 1080p native resolution (but does support 4k contents). It has good black level, refers to the darkness of the black colors it can reflect, and it can display movie with darker scene more clearer and easier to see more details in a darker scenes. Colors are also vibrant, as you can see from my photos.6) E-Sharing app: which is an equivalent to Miracast or Chromecast, it allows me to share contents from my phone to the projector quickly and is very simple to set up and use.Out of all of its Pros, I only see 1 Cons, which is the mobile app version of the remote control. I think the mobile app is still in its infant stage, not all features offer on the mobile app are working yet, but I hope since it's just a software issue, they can quickly work on it and release future versions that will be fully working and support this projector better.I ordered a new ceiling mount for it and can't wait to have it install on my ceiling, which I'd recommend if you have young kids in the house, it would keep the image and its setting static and help protecting the projector from being drop onto the floor accidentally.
