I would give 1 star because the HDMI doesn't work and there is no other way to connect another device, not even with an app, I spent countless hours... I only managed to make a useless mirror of the whole phone screen without the possibility of full screen... Netflix never connected, and we even updated and reinstalled it. Never. It always got stuck at login.

In the end, you can only watch YouTube and with a USB flash drive. I give 3 stars because when you watch from these two sources, the lamp is very powerful and the resolution is quite good so the picture is good..

Big foul that it doesn't have HDMI connectivity for using other devices; the port that exists is only to send image to another screen and not to receive

One star since both times I "bought" it, it didn't work (one time was a replacement). Good build and strong lamp but unfortunately the source is only YouTube and it doesn't recognize USB or HDMI making it "useless" neither from the remote nor from the physical buttons on the device possibly due to a software error since the ancient Android 7 it runs as an operating system is poorly configured. What a shame. It could have had everything...

Extremely honest. Pleasant surprise, where it was not mentioned, is that it has WiFi, therefore also Netflix and YouTube. It reads movie files normally through USB and subtitles with many settings. The unpleasant surprise and paradox is that its HDMI is an output and not an input (!), resulting in not being able to display images from the laptop...

For the money, it is very decent..
Negatives
1. HDMI is out, meaning it transfers the image to the TV. It is not in to connect to PC, consoles, etc.
2. Limitation of applications due to the Android version.

Positives
1. Very good image even in low light environments.
2. It has manual focus adjustment on the lens.
3. A variety of settings to adjust the image to your preferences such as:
- Keystone correction
- Four Point Scaling
- Whole scaling
- Projection mode (mirror, 180°.)

P.S. All settings can be found in the Apps icon, and in the Zoom settings option.

For the cost, it is a decent choice with respectable brightness and sound, but with some limitations that if I knew, I might have chosen something else.
1. It does not have keystone/tilt correction, so it limits its placement.
2. The HDMI is out and not in, so it cannot be used with TV boxes, Cosmote TV box, laptop, etc.
3. Some applications (e.g. Cosmote TV that I tried) do not work due to the Android version, and I have not yet found a way to upgrade.

If anyone has a solution to the above, please share!

Very bright you see even with the lights on but I ordered the model with 4 GB memory and 1080p native and they sent me with 2 GB and 720p also it runs on Android 7.1 with the latest update in 2022 from 6. In the settings, however, it says it runs on Android 9!? On the other hand, it is quite brighter, 60 watts lamp compared to the 20 watts of its brother s7 (which I already own..see review). and at 70 Hz! It also has 4 cores at 1 200Mhz and WiFi, Bluetooth. It plays 1080p and 4K with ease.
