I have been using the product for a few weeks. I was most surprised by the speakers, which are really solid. With all other competitor projectors, reviewers write that the speakers are not good, but here they work very well. Sure, you can't expect the full top end, but it's sufficient for movies, even pop music can be listened to from YouTube. Hand on heart, for people who want to project a film on the wall / screen / sheet at home (we project on a sheet for 300 CZK, moreover transparent and poor quality and it works), this is an absolutely clear choice that has no competition in the Czech Republic. What all this projector can do, you can not offer even 4x more expensive variant from well-known brands. Before I purchased the product, I wondered how it could be so cheap and yet do so much, I couldn't believe it. So I searched and the brand comes from China, so the low price is understandable because of China's cheap labor. If the Germans made it, I'd guess 3x the price. Honestly, the projector would be worth it even at 2x the price, it's really handy. Don't expect quite the peak picture you'd get from a UHD TV, but the picture quality is still solid (even on the transparent sheet we use). Considering our sheet, even if we project on it from the bottom and from an angle, it is very uneven and transparent, so the projector can still handle it. The auto-keystone and auto-zoom functions work reasonably well, and the image can still be sharpened with the buttons on the remote if needed, which is top (although I admit that manual and more sensitive sharpening directly on the projector would probably be better). For whom I would not recommend the projector: for people who want to project outdoors during the day, for people who want a high-end picture comparable to today's Full HD/UHD TVs, for people who don't have room to project and want more than 100% zoom (not possible here), for people who care about a proven brand, for people who plan to project at extreme projection angles.
For everyone else, it is the best choice on the current Czech market: )
