The Nebula Cosmos 4K SE doesn’t compromise whether indoor or outdoor on the patio. The picture, brightness, portability, and sound make watching movies a pleasure in any room.
Jeremy Kap
The quality of the Nebula 4K Projector is amazing. On a textured wall, the image is clearer and sharper than my 4K TV.
Steven A. Reich
I use the Cosmos 4K SE in the basement, and the image is clear and bright. The Netflix app works well and is much better than projectors that don't have a built-in Netflix app.
Klemen Krnc
It's truly an all-in-one cinema, and everyone is amazed when they see it in action!
Lior Hait
The Nebula Cosmos 4K SE is a game CHANGER. We’ve hosted many soccer games at our house and my family won’t watch a game anywhere but my house because of the projector.
Zack
The Nebula Cosmos 4K SE is very quiet and bright, the picture is really nice and impressive. Software seems pretty fast compared to my older projector.
Sean Garrett

Jerry Koh
