When mounted to the ceiling in the designated "ceiling mode" the angle adjustment of the built in gimbal is poor. The unit will not do any automatic sizing or screening in ceiling mode from 16ft. It returns an error saying that is too far.

Liquid cooling is a seeking point, but the cooling system is louder than competitors.

The operating system pays and stutters.

With a lot of fiddling, the color and contrast can be excellent.

I've been using this for the past few weeks. Over 500 hours of usage so far. I've been using this in a large variety of environments; as I floated between a few spots in my house and taking it on travel. attached a video of me doing a rave in my trees one night because ... 3000 lumens man.That's really how this thing shines. First and foremost it's a quality projector that is both bright and adaptable enough to fit 'non-perfect' environments. As it doesn't take long, nor in depth fidgiting to get it working well in a new area, means you can move it. You don't have to have the one spot you have to have it it, it's portable enough to move. You can get some pretty ludicrous but still excellent positioning on it to; doing some things you'd never want to do with other projectors. Currently mines sitting about 2 feet from my head, pointing at the ceiling. It's 12pm, with only light filtering shades up, and I still only have it on 50% brightness, yet watching a 4k stream of space. It's doing this while sitting on a box, slightly raised to ensure the heat dissipation fan is able to keep the liquid cooler running (because the heat vents out the back). There's so many different reasons this wouldn't work with other projectors on the market (Noise, lumens, ability to position it, ability to adapt to the position with focus setting, etc).The audio is surprisingly good. That and the water cooling I think contribute to the heft of the unit. Last picture shows a cloudy day, no blinds or curtains up, yet the picture is beautiful on the ceiling.Best recommendation I have if you do get this and you don't get the expensive carrying case, is keep the box this comes in. It has molded cushioning in it that helps greatly with carrying this thing around from house to house. That and if you opt for a vertical direction projection make sure the fan air remains unblocked in the back, as the side holes in it don't dissipate heat.I played all kinds of content with this to. Anything google android can play. I sideloaded a few apps on it to. Everything from 4k HDR youtube to lots of Dolby Vision files. I have a mesh network with dedicated backhauls operating at the near max of consumer grade wifi; there was no lag or latency on the device. When operating on less pristine wireless environments I noticed the SW had a hard time keeping the buffer or links to the media stable. I can't really blame that, it's just a factor moreso of Android they have loaded onto it and the apps it generally comes with. I can say I had no issues when attached to my top tier wireless. I had more issues doing hardline HDMI connections to it but that's more to do with ensuring everything in the chain actually outputs right (Connector, cable, and content all need to be outputing at 48 Gbps if you want stable 4k 60hz HDR; and it always is rough chasing something that gets dodgy).Having used it for nearly a month and hundreds of hours I can say there's nothing like this at this price point and the value is there if you want to have video projection in non-optimal environments, while maintaining portability, and you want some of the best video quality capable out of a projector you can get outside of the movie theater high $$$ ones.

The NEBULA X1 Projector is like having a super awesome movie theater right in your home! It gives you amazing pictures and is really easy to set up. It uses a special "Triple Laser" light, which means colors look incredibly bright and real, even if your room isn't totally dark. These lasers also last a very, very long time, so you don't have to worry about changing bulbs, and you won't see any weird rainbow effects on the screen.For clear pictures, the X1 is a champ. It shows images in "True 4K UHD," which means everything is super sharp and you can see every tiny detail, just like looking out a window. Movies, sports, and games will look fantastic. It also makes dark and bright parts of the picture look better, so everything feels more real. You'll be amazed at how clear and detailed everything looks.What's great is how easy it is to use. Setting it up is a breeze because it can automatically make the picture clear and perfectly shaped, even if the projector isn't quite straight. It also has smart TV apps built-in, so you can watch Netflix or YouTube right away without needing extra gadgets. The remote is simple, so you can start enjoying your big screen quickly. Even though it's a fancy projector and costs a bit more, it's a great choice if you want top-notch picture quality and an easy experience for your home cinema.

🔹 The Initial Disappointment – Broken Seal & Questionable First UnitWhen I received my first Nebula X1, I immediately noticed something was wrong:• The security seal was missing on the box.• It looked repackaged and possibly used, though sold as brand new.This raised serious red flags about the product. Still, I gave the unit a fair chance — I ran color tests, adjusted settings, and tried to dial in the image.But the picture quality was disappointing: pink tint, washed-out colors, and poor handling of daylight brightness.It honestly didn’t feel like the X1 everyone was raving about. I returned it.🔹 The Second Unit – A Complete TurnaroundThe replacement projector arrived sealed and pristine, and I knew instantly this was different:• Sharper, cleaner, and more vibrant visuals right out of the box• Once calibrated, the image quality was nothing short of stunning — even in a daylight-lit room• Paired with an ALR screen, it delivered cinematic clarity and accurate color depth• Whether watching HDR films, news, YouTube, or test patterns — it held up impressivelyThis unit showed the true potential of the Nebula X1, and it’s absolutely worth the praise it’s received — when you receive a proper unit.🔹 Calibration Changed Everything — Try This Before You Return YoursOut of the box, the X1 may look too warm, too pink, or overly sharp — but the hardware is incredibly capable once calibrated.🛠️ I spent hours testing grayscale, color bars, SD & 4K content, UI screens, and real-world footage — and I’ve built a full calibration profile that turned this into a 10/10 image.👉 My Final settings for daylight viewing was just as simple as moving to Conference Mode and bringing down the Green color temperature to make whites look white! Play around a bit with the Color tuner and the 11 Point white balance.. I’m sure you’ll find something that works well for youBefore you consider a return, try these settings — you may be surprised how much performance is hidden just beneath the defaults.🔹 Final VerdictPros:• Gorgeous picture quality after tuning• Great brightness and contrast, even in well-lit rooms• Smooth motion handling and detailed shadowsCons:• Inconsistent quality control from sellers (watch for open boxes or missing seals)• Requires manual color tuning for best experience• Lacks profile-sharing support nativelyThat said, once you get a sealed, proper unit — the Nebula X1 is easily among the best portable 4K laser projectors in its class.🔹 A Word About Returns, Buyers, and IntegrityThere’s a lot of talk these days about how returns are hurting sellers on Amazon. As a buyer, I want to offer a fair and honest counterpoint:🧾 When I buy a product like this, I do so because I’ve already decided I want to own it, not test it.I choose Amazon — not a used marketplace — because I expect a brand-new product, sealed, untouched, and as described.Unfortunately, sometimes I’m forced to return items because what I received doesn’t match that promise.This isn’t about abusing returns — it’s about standing up for what’s fair.💬 Not all return issues are due to dishonest buyers. Often, it’s the seller’s handling, poor quality control, or misleading listings that put honest customers in this position.Thankfully, Amazon has usually supported buyers like me — and I’m grateful for that. But I felt it was important to say:“Integrity goes both ways — and buyers have standards too.”

It is best projector I have ever seen. Picture and sound is amazing. I love it.
