Nebula Mars 3 Air

I've had this projector for close to a year, using it on a daily basis for watching TV shows and movies, in tandem with a folding screen and wireless soundbar. Overall, I've been impressed with the picture quality and ease of use offered by the projector, as well as it's compact and unobtrusive format.The automatic image correction and focus are generally reliable and function very well for a projector at this price. If the projector is positioned at a significant angle, to the side of the screen/projection surface, there is some "softening" of the image in the upper corner farthest away from the lens. However, this isn't really noticeable in normal use, and positioning the projector more centrally avoids the issue altogether. Similarly, projecting from a significant angle often requires use of the manual correction to ensure the image is fully symmetrical. However, after a little bit of use, making these adjustments becomes second nature and takes only a few seconds.The sound quality of the inbuilt speakers is surprisingly good and loud, again given it's diminutive size. However, using a external speaker setup will significantly enhance the movie viewing experience. The Bluetooth connectivity is excellent, and it unfailingly links to my soundbar upon start-up, and there is no noticeable lag or synchronization problem between the image and sound.Similarly, WiFi connectivity is strong and stable (even though my router is on the other side of the house and on a different floor). Media plays without hiccups from USBs or when input from another device that's connected via HDMI. I don't really cast content from my phone, so can't comment on this aspect of the projector's performance.The inbuilt battery is okay - but watching anything of movie length requires the projector to be set in power saving mode, which significantly dims the image, even in a fairly dark room. At full brightness, you can expect to get through an average episode of a TV show (45-60 minutes) but no more. To get best use out of the projector, it needs to be plugged in to mains power, which obviously limits its portability somewhat.In all, I'm very pleased with my purchase and would definitely look to buy a newer model Nebula when I finally want or need an upgrade.

Currently projecting onto the ceiling and the picture is bright and clear with a darkened room.The sound is also really good from the built in speakers.Haven't tested other conditions yet, but so far very pleased with the quality, ease of use and size of the projector.

I love projectors and after so many research when i bought it .. it delivered on time .. appearance and holding in hand was good .. battery wise it was good and very easy for setting it up ..image quality and sound was great.. only problem i faced like when a little movement happens it kept going on adjustment and for this u must need a tripod and a steady place where it doesnt move .. capsule 3 the way it was advertised like holding in hand and watch but with this if a little movement happens it straight go to adjustment and you lose the excitement of warching something u are into it.. another problem i faced and for that reason i returned my item at the moment because in my nebula.. disney plus.. bbc player .. itv player was not working and kept giving problem saying region problem .. i am in UK and in my region these apps are working but mine projector was not working and contacted Nebula too so due to that reason i had to return my product but if someone projector is supporting all these apps .. you will love using this projector.. but u will need a tripod or a place where it does not move..i will recommend to try and buy

This was a little bit of a stab in the dark as I was looking for a small portable projector for the bedrooms and the mars 3 air had just come out and had no real reviews yet. I was first tempted by the Samsung Freestyle 2, but a lot of reviewers noted that for its price (~£700) it wasn't that good a projector. IIRC it only goes up to 240 lumens. But it had good apps and connectivity, so it was hard to find something with a similar feature set but cheaper. The Mars 3 was generally recommended as an alternative, but that's a similar price point to the Freestyle for a bulkier, brighter protector that's better for outdoor use, which I don't care about that much.That's where the Mars 3 Air came in - at £450 it's much cheaper than the freestyle, almost twice as bright, and has excellent connectivity and app support, with even native Netflix, which the more expensive Mars did not have.Some things to watch out for - first time set up is a bit slow, confusing and clunky. Google Home setup via the app is pretty okay, but it took a *long* time to download and install firmware updates. Once it was up and running, it still behaved weirdly, e.g. I could not access the settings menu, or sign in to YouTube, or download new apps at all at first. The trick seems to have been to reboot it several more times. Once fully set up it all works as expected.The auto keystone features and auto focus in my experience aren't great - they're a good starting point, but at least in my space, I usually do need to go in and manually adjust them. If this is the case for you, I would recommend turning off auto keystone and auto focus on startup and after movement, so you don't have to recalibrate every time you nudge it or turn it off.Overall though I think it's a really good deal for the price - responsive UI, very solid brightness and colours, great sound. Connectivity and apps all work fantastically, and having Netflix natively on the device is great! You can also Chromecast easily from a laptop or phone. Expect a bit of faff during first time setup, but after that it's a really solid device!
