Absolutely impressed with the Nebula Cosmos Laser 4K ! Setup was super easy with auto-focus and keystone correction. The 4K laser projection is sharp and vibrant, even with some ambient light. Android TV runs smoothly, and the included dongle gives access to all major apps. Built-in speakers are decent for small to medium rooms. The design is sleek and portable with a sturdy handle. Perfect for home theater or backyard movie nights. Highly recommended for anyone looking for premium quality at a better price point!

⭐️⭐️⭐️⭐️⭐️ Incredible 4K Projector — Feels Like a Theater at Home! I’m extremely impressed with the NEBULA Cosmos 4K SE. The picture quality is stunning — super sharp 4K resolution, vibrant colors, and great contrast thanks to Dolby Vision. Even in rooms with some light, the 1,800 ANSI lumens keep the image bright and clear. Movies and sports look amazing on a huge screen, and it really feels like a full cinema experience. The setup was simple, and the built-in Google TV makes it easy to stream anything right away. The sound is surprisingly strong for a portable projector, and the handle makes it convenient to move around the house or take outdoors for movie nights. Even though it’s a renewed unit, it looks and performs like brand-new. For the quality and features you get, this projector is absolutely worth it. Highly recommended for anyone wanting a premium home theater setup!

As others have mentioned the picture is crisp and clear even for 1080p movies at a large size, they look great. As expected, lights in the room on the screen do quickly degrade the quality when not using a good screen. 3D on this model is easy to set up using the device settings and is the best 3D I've seen when paired with good active 3D glasses. One last thing is sound quality. From the reviews, I had expected a decent loud audio from the unit and am now using a separate speaker for audio. For refurbished, this unit looked new and is very easy to set up.

Good projector accept that you can’t see much during daylight hours while set up outdoors or even inside.. I have to close all my blinds during the day to see this the picture well and even that really isn’t enough.., Another thing I don’t like is that on these refurbished units they don’t offer that long of a warranty. You get a 90 day warranty on them and at about a year my power supply blew and now I’m out all that money for a projector. The manufacturer won’t even take it back for repairs for any type of repair. I sent it to 3 different repair places and nobody wanted to work on it. After all this I bought a brand new one and it even has some quirks. It just shuts off sometimes or will back out of what your watching a few minutes after start up. Just boggles my mind that even the manufacturer doesn’t even want to work on repairs. If you do purchase this projector the do yourself the favor and definitely get the extended warranty or the insurance on it. Trust me on this. I’m kicking myself now. Also I wouldn’t even buy a refurbished unit ever again. Only buy these new. Really mad that they won’t even take it back for repairs. Shame on them.

Got this on sale at around 800 bucks. Works well considering its a 4k projector that's portable and all in one. The image is decent but you have better options out there if you got the money but most are almost double what I paid for this. The U.I is slow and unresponsive at times plus its pretty slow to boot up too but once its on all you gotta do is point it at a wall or screen and youre good to go. I will say it has some issues recognizing 4k out put from my pc and when it does it caps it at 30fps so I havent been using it for gaming all in all if you catch on sale and need a 4k projector that won't break your bank id say this is an ok option but there's definitely better out there and forget competitive gaming on this thing as the response time is ok at best. All in all dont let the reviews on YouTube make you believe this is the end all be all portable projector like I did but im still impressed with how convenient and easy this thing is to use once you get past the quirks.

The NEBULA Cosmos 4K SE delivers crisp 4K UHD picture quality with Dolby Vision support and vibrant color reproduction, making movies and shows look stunning on a big screen up to 200″. Its HybridBeam light engine and 1,800 ANSI lumens brightness bring rich images even in moderately lit rooms, while built‑in Google TV offers seamless access to streaming apps without extra devices. Setup is easy with autofocus, auto keystone, and wall‑color calibration, and the included speakers provide surprisingly solid sound for casual viewing.  However, contrast and black levels can fall short in darker scenes, and the software UI may feel sluggish at times—issues that keep it from being truly premium. Still, it’s a great all‑in‑one 4K smart projector for home cinema on a mid‑range budget.

I read great reviews about the Nebula Cosmo 4K SE, so when I saw a refurbished model on sale I jumped to the chance to buy it right away. The price was too good to pass up. One thing that is understated in user reviews is the low contrast ratio. Even in a dark room with velvet wall curtains to absorb bounce light, the blacks levels on the projector are worse than bad. Another note is that this projector isn’t true native 4K. It uses a 0.47-inch native 1080p micromirror DLP chip that achieves 4K-like picture quality using pixel shifting technology. It’s 1080p native but shifts the sensor to a degree that it fakes a 4K image. Given the price point at which I bought it at, the image quality is fine minus the black levels. Another flaw about the projector is that it requires 1.5 meters for the auto keystone to come into effect. Out of the box I thought I got a lemon unit because the projector kept giving me a sensor error as it failed to keystone or focus. After moving the projector approximately 1.5m away from a wall the auto keystone worked as long as I go into the screen menu. Using the auto keystone button on the controller always led to a sensor error. Perhaps I did get a bad unit or it’s just a quirk of the firmware. The problem with video reviews on YouTube is that they don’t mention any of these issues about the required distance and janky auto keystone functions. I’ve had the projector for about 2 weeks and I must have seen the “Contact support” popup window at least 30 times. But, again…due to the price point, I can live with a few quirks. If your budget is under CAD$1400 after taxes this unit is fine….but if you have a larger budget of $CAD10,000 before taxes, save your money for a true 4K projector. This unit was in my price range….if you can afford something better, don't buy the Cosmos 4K SE.
