Very good product for the price (under $200). The brightness is just under 500 ANSI lumens according to my measurements. The picture quality is good, but not perfect. Saturation of colors could be better as it covers only about 60% of Rec.709 gamut. The sharpness is also not perfect, but absolutely usable and much better than cheaper projectors like Hy3xx. Software is really good and stable, at least version v3.10 in my case. Automatic focus and keystone correction is usable, but its better to fine tune it using manual controls. The noise coming from the fan is not terrible but definitely noticeable. The most annoying thing in this version is the remote. Its not ergonomic because of the shape of the buttons - the joystick buttons are concave and hard to find by touch. The projector works perfectly with Chromecast and supports CEC, so you can use Chromecast remote with the projector.
mirrorcast is ok... brighter than i thought (im screening in a White wall while its a Greek sunny day...4k looks good,sound is medium volume -bass but not. problem for me cause i ll connect Bluetooth speaker system.i m surprised by how silent the projector is.... overall very pleased with the purchase...
