Amazon.co.uk:Customer reviews: Nebula by Anker Mars II Projector with 720p DLP Picture and Dual 10W Speakers, Android 7.1 OS, Single-Second Auto-Focus, 30-150 in Screen, 3 Hour Playtime, Broad Connectivity, and Wireless Screen Cast
It’s not the brightest for daylight viewing although manageable if necessary. However in dimly lighted rooms and dark rooms the screen is bright and crystal clear. I actually used this for a running club presentation with over 100 people in the room. It was absolutely fine and the fact it’s portable meant it could be easily positioned. The HDMI connection worked perfectly. Sound is pretty decent but obviously only 10w so it’s limited. Absolutely love the auto focus. Didn’t disappoint!
I would love a slightly better picture quality but that would take me into much higher price brackets. For the price this is excellent. In the dark its a fantastic picture. With a bit of background light its still manageable.
The interface is really great, just works smoothly as a plug and play.
The product design is lovely, its really perfect as both portable and static
Great projector, so versatile. The kids love it. We watch netflix and play our snes mini or PlayStation on it. Easy to pick up and move with a fast auto focus. The battery life is great and it isn't too difficult to add new apps. It also works great as the Bluetooth speaker, I had it running all day not plugged in with no problems. The only negative is it could be a bit brighter but no problem in the evenings.
