The Anker Nebula Mars 3 Air is a portable masterpiece compared to all those other crap chinese projectors for 100-400 GBP. Ive went through around 6 if not 7. Save a little bit up and buy this piece of machinery. It has impressive performance when it comes to the OS lag and speed (better than my smart TV), Its sleek design makes it easy to take anywhere, perfect for movie nights and presentations on the go. The 400 ANSI lumens brightness and 1080p resolution ensure a bright and clear picture, whether you're watching movies, playing games, or giving presentations. (When a playstation or xbox is detected, the projector turns into gaming mode providing a very smooth gameplay, VERY low (I'd say immediate, as good as a tv) input lag. And the HDR is really noticeable during the night, little less so during the day due to the lack of lumens to handle HDR)Connectivity HDMI, USB, and wireless casting via AirPlay and Miracast, offering flexibility to connect a variety of devices seamlessly. The built-in dual 5W speakers produce rich and immersive sound, enhancing the overall viewing experience without the need for external speakers. Especially the PS5 (sounds phenomenal).While the Mars 3 Air's battery life may be limited to around 3 hours, it's a small trade-off for its portability. The built-in fan can be audible during quiet scenes, but it's a minor inconvenience considering the projector's overall performance.Only downside I could think of is the focus, it seems to struggle to keep the whole image focused when further away (around 7 feet). I'm unsure if it's a software bug or the camera within the projector which may be low quality which causes the struggle.If you have a PS5 though, this is definitely your Go-to if you're on a 500GBP budget. I managed to enable surround-sound with dolby atmos audio, HDR10 and 4k video output on YouTube and netflix (the projector doesn't support 4k but higher bitrate video really improves image clarity making the image even better). So for those who have surround sound and want a projector, the projector in the settings has a dolby digital plus setting and you can tweak the bass and treble to your preferences, but if you have surround sound and a PS5, connect it to the projector and... congrats you have a cinema at home �
