I have owned projectors since 2009 and had many that range from very high end to very low end. I have a JVC NX7 / RS2000 coming very soon as well as a Da Lite High Power 2.8 gain 120" so I know what a good picture is suppose to look like. I also have many asian pico projectors that I have been trying over the years. Many of these projectors even have faster processors, ram and ROM space than the Mars, but that is all meaningless is you don't have the software to back it up. The Mars II is buttery smooth and responds to all commands very quickly. Other projectors normally fail in this regard when trying to use the home button on a resource intensive app. Also many of the pico projectors are strictly SVGA / XGA or some form of this resolution. The picture with text is very pixelated that smooths out a little when watching cinema quality content. This picture however is extremely lacking at usually a high price tag (~$100-$300) It simply isn't worth the trouble. Go with a reputable company that be there when things go wrong and will actually update their devices as time goes on. I have had nothing but things to say about all the Anker products I own (which is a lot). They are all very high quality and so far none of them have broken yet (except a battery charger that I dropped, but still functions though the indicator button is busted now)Pros * Compatible with all the apps I require: * Youtube * Hulu (Updated versions of this require Google Play Services) * MX Player (This is broken on many Chinese projectors) * Emby * VRV (This is RARELY compatible with other android devices) * Netflix * Kodi * Xfinity Stream * Very bright image, easily viewable on an off-white color wall * Auto keystoning / focus * Very long battery life (usually lasts a movie of 1h30 to 2h) * Excellent customer support with potential access to early beta builds * Aptoide version of Play Store is superior to any Chinese variants you'd find in other small projectors * Ability to side-load apps * HDMI in has auto switching that will sense an HDMI signal and switch over to it * Buttons on the actual unit so remote is not required * Nebula Connect App lets you control the projector with your phone * Casting from a OnePlus 6 just works WITHOUT the need for any other software (This is not the case for ANY other projector I have tried - usually Miracast or some other form of app is needed, and the app is not native, so it is slow and only works much like Google casting, where it must be a compatible video from a service like Youtube, rather than the desktop. I cannot stress enough how rediculous this has become - for some projectors I have tried nearly 10 programs, which all fail to do even the most basic of streaming well. With the Mars II I have streamed with Wi-Fi direct video games, such as Sonic Dash | To do this go to Settings -> Display -> Cast [at the bottom of the list]. Also under Settings -> Wi-Fi -> Advanced -> Wi-Fi Direct, select the 'NebulaXXXX' device.)Cons * Fan can be noisy compared to other small form factor projectors (it becomes more in-audible the louder the movie is, if playing content at even 1/4 max volume it will drown out the fan. This is to be expected with the amount of lumens this thing puts out) * Carrying strap is not detachable or hide-able (would be nice to have it depress into the unit so it doesn't look so tacky while in use or not needed) * Google Play Services is not available on the base firmware (this is needed for a lot of apps, which makes them un-usable without it) * Mouse mode on the remote control is cumbersome, you must press the button and then move the cursor with the directional pad. A better alternative to this is to buy a USB remote that allows you to point at the projector screen in order to move the mouse, this is much more intuitive. This is what I use: https://www.amazon.com/Backlight-Wireless-Controller-3-Gsensor-Projector/dp/B076BRLHZT. However, if you simply use the Nebula app, which has a mouse mode by moving the screen this works your finger over the screen - this works just as well.The customer service is fantastic. I sent a message to them about a firmware update to address the issue with Google Play Services, and even on a weekend they got back to me within hours. They allowed me into their beta program and so far the new firmware is great. Thanks very much to Helen for assisting me in this matter, she has gone above and beyond in making sure I was satisfied with my purchase.Overall this is the best projector for the small form factor market I have tried. I currently have 5 projectors and 4 of them are small form factor. This one is superior to them all by a mile. Best of all, these projectors use LEDs which has lamp hours in the 10s of 1000s. Basically, you will never need to replace the lamp (you can't you will just need to buy a new projector) unless you watch it 24 hours a day for the next 3.5 years. With my new JVC projector coming the lamps normally last 3000-4500 hours in which you will need a replacement which will cost us around $800, nearly twice the price of this entire projector!NOTE: The video / images are not accurate to what you will see in person (it looks much better) but I hope it gives people some better clue of what to expect!
