Excellent Pico
After 1 month of testing, I am not disappointed with this mini projector. It is small, sober and of very good quality.
I was surprised by the brightness for its size, 300 lumens in led, I would say that it is the equivalent of 1300 lumens in halogen. The 720p is sufficient up to a screen size of 100 inches after that it's rather limited.
The autonomy given of 2h is respected provided that it is in economy mode (200lumens) (held 2h15 personally in hdmi), and in normal mode it lasts about 1h30.
Big positive point:
Excellent sound quality in film and music, which covers the mini cooling fan.
Negative points:
You can hear the fan if you use the sound at low volume, can be disturbing for some.
And finally the operating system (which is not Android) is really only used to read files on internal and external media, Apps such as Netflix, Disney or Prime, have big compatibility problems (hardly works).
Fortunately, you can directly cast content from your smartphone to compensate.
