The projector is actually excellent for the money. You need to know why you want to try it – in other words, I wouldn't buy this particular one for gaming. Otherwise, for me, it beats any display, including any television/monitor. For the price, it's unbelievable what it offers, and in retrospect, I actually regret not getting a projector for watching videos long ago. The resolution is 'only' 1080p, but the large format completely makes up for it. You basically have a 100"+ television in a relatively small box that you can take anywhere. Projecting onto a wall is sufficient; even on a relatively dark blue one, it works without problems – a screen is better, but not necessary.
The brightness is good for the price. You don't need complete darkness for a very good picture. At the beginning of September, it was possible to project outdoors as early as around 8:00 PM. In a room, you just need to darken it a little. The projector has already been used for 4 outdoor screenings and countless regular ones on the wall and ceiling. The picture quality is excellent for the price – I'm a bit sensitive to colour (even things like lighting) and I notice the colour tint is a bit blueish; I'd like a little more red. However, for the price, it's absolutely OK, and once you get absorbed in the film, you more or less stop noticing it. The integrated computer with Android is a nice (but not essential) bonus. You need to bear in mind that it's no speed demon and is less powerful than my old FireTV Cube – so you need to feed it videos in a suitable resolution, i.e., max 1080p h265 (it can't decode 4K, and since its max resolution is 1080p anyway, it doesn't make sense). In terms of sound, you need to expect that it's basically a mono speaker – albeit a relatively good quality one. Nevertheless, it was more than enough for outdoor screenings and creating a cinematic atmosphere. For more demanding users, there's the option to connect external speakers/an amplifier via a 3.5mm jack. For anyone who can imagine what they would use such a thing for, it's a cheap ticket into the world of large-format home cinema. Personally, I have only one complaint, and that's directed at Alza, which doesn't sell the original bag/case for storing and travelling with the projector – I had to buy it directly from the manufacturer in China. It's a great shame that you can't get the complete offer/service including accessories in a Czech shop.
