Best projector ever
Better than I could have imagined easy user interface officially licensed apps make it easier to stream travel handle very useful and very clear bright pictures with vibrant colors. Great value for what you get especially if you use it Outdoors.

Best deal for 4k 2000+ lumens (refurbished)
Review for the REFURBISHED Nebula Cosmos Laser 4KI first got hooked on laser projectors with the Epson EF11, which I bought for about $800 new. Missing 4k and the brightness of a standard screen, I decided to track consumer grade projectors that had those features. I recently upgraded to a renewed Nebula Cosmos Laser 4k for the same price, $800. The projector is the best deal out there at that price. The unit is larger and heavier than expected, but the auto focus and auto keystone functions quickly adjust from having the projector off to the side due to its size. Because the left side of the projection surface is closer, it's somewhat brighter - noticeable only because the image is so bright. The on-board sound is good, with noticeable bass. Finally, I was surprised how quiet the fan runs compared to the Epson, which was 1/2 the lumens. Now I'm coveting the X1.Ver másVer menos

Doesn't justify the price.
The Nebula Cosmos Laser 4K is a disappointing upgrade that fails to justify its premium price tag and the refurbished one does not live up to Anker/Nebula build quality.. While it boasts 2,200 lumens brightness, the actual measured output in standard mode only reaches around 1,700 lumens, which isn't significantly better than the much cheaper Cosmos 4K SE's 1,800 lumens.The gaming performance is particularly underwhelming, with input lag measuring 65-68ms even in game mode, making it unsuitable for anything beyond casual gaming. This is especially frustrating when compared to the Cosmos 4K SE, which achieves an impressive 18.4ms input lag.The build quality leaves much to be desired, especially coming from the Mars 3 which features robust IPX3 waterproofing and drop protection. The Cosmos Laser 4K offers no such durability features despite its higher price point.While the laser light source promises 25,000 hours of life, the same longevity can be found in the more affordable Mars 3's LED system. The contrast and black levels, though better than some LED projectors, still fall short of expectations for a premium laser projector.For the price, you'd be better off considering alternatives like the Hisense L9G, which offers superior color performance. Even the more modest Mars 3 with its 1000 ANSI lumens and built-in 40W speaker system provides better value for money. The Cosmos 4K SE, at a lower price point, delivers comparable brightness and actually superior gaming performance, making the Laser 4K's premium price tag hard to justify.Ver másVer menos

Great projector
I needed a projector to show movies at dusk. And this one works great for that. The apps i can put on it work great. The one problem I have is when you use a hdmi device you can’t use the Bluetooth to connect to speakers. Luckily I had long enough audio cable to reach external speakers.Ver másVer menos

super easy and perfect for movie nights
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!Ver másVer menos

Decent video, but software is lacking
I bought this alongside another cheaper non-laser projector, tested them both, and decided to keep the other one. Here are the pros and cons of this projector:Pros:- Picture quality was very good, contrast was better than the LED alternative. Audio was impressive as well.- Came with android TV 12 instead of version 10, which was a pleasant surprise.- I liked the idea of the dongle being replaceable, but I couldn’t find anything that indicated they intend it to be upgradable in the future.Cons:- The device doesn’t work without the dongle, for example, you cannot just hook up an HDMI device and project if the dongle is missing or broken.- Unlike the other LED projector I kept, this one cannot connect to a Bluetooth audio device like headphones or speakers if it’s taking the input from HDMI. So if you intend to use another dongle with this, you are restricted to the internal speakers or have to hook up to the aux port in the back.- YouTube playback even with 1080p was choppy, and the audio was choppy as well on Bluetooth headphones. I think the processor is not fast enough for the codecs.- The projector doesn’t have much of a vertical throw, meaning if you put it level on a table (like you would ideally want to), the bottom of the image will be below the projector’s level. So the tall projector and its bold handle will likely block the view.- The heavy and upright design of this projector makes it unstable on a tripod, it’s mostly intended to be used on a table, which makes positioning and adjustments difficult.All in all, audio/video is great but software and capabilities are limited for this price point. This could still work great for you if you want something simple, decent-quality, and portable, and the details above don’t really matter to you.Ver másVer menos
