NEBULA Mars 3 Air GTV Projector – Netflix Officially Licensed, 400 ANSI-Lumen Brightness, Native 1080P, Dolby Digital Sound,150-Inch Picture, Built-In Battery for 2.5 Hours of Playtime Anywhere.

Great projector!
Very easy to set up. Picture quality is great. Auto focus feature is great and every app I use for streaming is built in.

all around, pretty good device
only major complains are it can’t compete with sunlight so outdoor watching has to wait until night time, and it’s auto focus is nice, but it seems to always want to redo it right after we start watching something, which is a tad annoying. Otherwise, i appreciate the HDMI in and Audio out so it can do a bit more, the built in GTV is nice, and the battery life is just enough for a typical movie.

Great projector.
The Nebula Mars 3 Air project works great.

Consider other portable projectors, this one has major flaws.
Projector reviewI had the old Nebula Mars 2 projector and loved it! I used it probably 100 times over 5 years for watching movies outside. The brightness, battery life, sound, and build quality were top notch. It also had a very easy to use app system.Over the years the battery capacity decreased a bit (understandable, like any modern device) and it eventually got banged up enough that I was motivated to replace it with the new Nebula Mars 3 Air GTV.On paper, the Mars 3 is 25% brighter, 1080p vs 720p of the 2, and runs Google TV instead of Android, along with a myriad of other improvements.Upon receiving the Mars 3 I was impressed with its size and weight, it seems slightly more compact and a little lighter weight. I can confirm the picture is bright, not bright enough that I would want to use it indoors in a room with a lot of windows, but fine for a darkened room or evening outside. The setup features (auto-focus, keystone correction, etc., also seemed to work quickly and as designed). Unfortunately, this is about all the positive feedback I have on the Mars 3.My main issues are:- Build quality: The handle feels flimsy compared to the Mars 2 and is a bit loose. This is not the build quality I’m used to.- Sound: Allegedly the 3 has Dolby Digital sound but I found that the sound quality (particularly the bass and maximum volume level) isn’t as good as the 2. I’m only using the Mars 2 as a point of reference, I’m not comparing it to anything else.- Apps: This is my biggest gripe. The Google TV interface is horrendous. It’s slow, counterintuitive, and crashes constantly. It crashed just navigating between apps, doing searches, trying to type in credentials, and also while streaming video. In case you were wondering, it was within 5’ of my WiFi router and I have almost gigabit symmetrical speeds, so this was not a connectivity issue.Overall: I feel like the build quality has taken a step back and the app interface needs to be reconsidered. I’m not sure how much of this is Google’s fault and how much is Nebula’s, but interfaces like FireTV, Roku, and AppleTV are all faster and far more stable. I’m debating returning this, especially because the sound is so lousy, it really doesn’t have enough redeeming factors for me to want to keep it.

I bought this as a gift for my loved one for Christmas 2024 and this projector has been absolutely fantastic so far. I’m blown away by how bright it is!Picture Quality: The picture is bright, sharp, and detailed with natural-looking colors. It’s everything you’d want in a projector.Appearance: It’s small and lightweight, making it perfect for a nightstand. The top grip makes it super easy to move securely from one place to another.Audio: The audio is phenomenal! The speakers deliver impressive sound with deep bass, clear highs, and plenty of volume. Even at low volume, the sound is rich, which is great if you don’t want to disturb someone in the next room.Technical: The fan noise is practically non-existent, which is a big plus.What I love most about this projector is how social it feels. Thanks to its top handle, it’s so easy to carry around the house, and it fits perfectly into any situation. It brings people together with its wide image and built-in streaming platforms—your friends can pick whatever they want on YouTube.Highly recommended for anyone looking for a versatile and fun projector!

I originally ordered the much more expensive Cosmo 4K SE, which also was an excellent projector, but was much larger and was slightly overkill for the use I wanted a projector for and it didn’t have a battery which was a shame.So I ordered this one, which I was already interested in, it might be a 1080P projectors but I am more then happy with the visual quality of the projector, the size to distance ratio is perfect, to project onto a wall in the basement to watch some movies or shows with my GF, we are not using it to the full size it can do but I have test that to and it was more the clear to me. As for the brightness of it, I will say it could be brighter but it’s still more enough to watch with a light on or two without it being drowned out. The size of it is absolutely perfect for me, I bought a cheaper stand which make it look smaller, out the size with the fact it has a battery, it makes it super easy to just move around and store it away unlike the Cosmo I originally had. Which with how good the auto focus and keystoning is, I never had an issue where I had to fiddle with the settings or placements. Even the speaker were surprisingly good, the volume can fluctuat from loud to quiet and back but that is more on the content I was watching then the actual speakers themselves.Over all for the price I paid for it and what I got for it, I would say it’s absolutely worth it with plenty of value to it.
