Prime Day 2025, Asurion issue
Prime Day, 2025.Asurion cancelled my 3 yr. Ext. warranty, with no reason given; which is forcing me to return what looks like a stellar product.I’ve only tested the unit (as it was listed as “Renewed”) for DOA. But it should be duly noted, that the Cosmos 4K SE, is impressive. For a budget minded projector, it checks all of the boxes:Surprisingly good internal speakerseARC, for easy 2.1 soundAlmost idiot proof interface, for quick setup (e.g. auto white balance & keystone)Carry handle, for portability

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.

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.

Ok projector but not so much during the daylight outdoors
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.
