The picture is beautifully sharp and clear even though it's only FullHD
Luminosity is good in daylight
Very fast installation
The sound is not very good but everyone where you set up a home theater so buy some decent speakers
Not smart (solved by buying a cheap androidTV)
Only one HDMI

Unwatchable in daylight and in a darker room.
The overall processing of the product looks very cheap. actually looks more like a toy for children
I don't notice any difference when switching between ECO and normal mode, but maybe I just had bad luck with a defective piece. anyway, the luminosity was not up to par and even in complete darkness the picture is not completely great
The image is not very sharp and there is significant chromatic aberration in the image around the edges
the speaker in the projector is a horror even for emergency listening. the sound is literally ear-splitting.

the projector is probably suitable as a home cinema but if you use it as a presentation tool it is an unsuitable device as you can't turn off the image - black screen or image freeze. if I don't project from the center, there is no possibility to adjust the gain and only 1 HDMI cable can be connected.
silent
sufficient brightness during the day
price/performance ratio
it is not possible to give a black screen. For presentations, the key thing is that users can't see what's being done or reconnected. The only option is to cover it with a book (it doesn't even have a lid) or turn it off completely. For me, a reason to return
no vertical bevel option when the projector is not centered (horizontal only)
only 1 HDMI cable
USB does not have a strong enough power supply for chromecast 4 google TV (but even 20k projectors do not have this) - I had to connect externally
not a bag

We bought the screen outside, but unfortunately the light output is insufficient and it needs to be fairly dim, so I returned the projector. I bought a 3x more expensive 5200 ANSI projector and it' s still not enough.: )
From the image point of view, a good price-performance ratio. No frills, one hdmi input 3.5mm jack and that' s more or less all.
Poor outdoor projection performance.

I'm happy and grateful that the manufacturer didn't cram anything "clever" into the projector. Nowadays, to look for such a device is like looking for a needle in a haystack. Connect, set up quickly and easily, and enjoy the movie: )
Absolutely stupid device! Great! No "smart" harm!
Quiet in ECO mode
Decent image
Probably the best price/performance ratio
They must have found the remote control in a junkyard in China - just touching the "thing" makes me disgusted. But fortunately, thanks to the CEC, there's no need.
The repro is funny, even my ZX Spectrum played better: D
Free canvas +/- too big for me.
