These are generally serviceable products with a range of input options, decent pictures, and OK-sounding speakers.
On the left and right sides of the projector are the generously sized speakers.
There are also a pinhole reset and a Power button, as well as air vents.

Underneath the projector is a standard tripod connector.
Instead, we get a standard two-part AC adapter with a barrel plug.
The remote control, which takes two included AAA batteries, is similar to otherGoogle TVremotes.
The Nebula Mars 3 Air looks the part of a premium portable projector and sounds great, but has performance issues with its built-in Google TV apps and lacks enough brightness for use outside very dark environments.
Nevertheless, the projector does a good job automatically compensating for both obstacles and angles.
In short, there’s little you might’t configure.
The colors were accurate, especially for HDR-enabled content, and the screen was easily visible.

Naturally, with more light in the environment, the less saturation there was on the projected image.
The fan noise is at least quiet enough to not be distracting.
This is good because audio is really one of the Mars 3 Air’s strong suits.

While 100% volume is not exactly overpowering, dialog and sound effects remained easily discernable at maximum.
Use Cases: Entertainment and Light Gaming
The Mars 3 Air’s processing power raises some questions.
Some apps, like YouTube, did perform better than others in this regard, however.

Of course, there’s more to the Mars 3 Air than built-in Google TV.
Fortunately, these other functions generally work better.
you’re able to also sideload apps that aren’t available on Google Play using this method.

Overall, this worked well.
For example, I used a wirelessPolymega controllerwith a USB dongle to play “Sky Force Anniversary.”
This projector proves a nice option for casual Android gaming with a controller.
When playing external video content, lag is irrelevant as it doesn’t require constant input.
Finally, there’s a reason why the Mars 3 Air is generally billed as an outdoor projector.
For my family of five, it was our favorite use of the projector.
As such, for those primarily looking for an indoor option, I’d say look elsewhere.
