Connecting it to my wifi was easy, same with setting it up to a laptop or my phone. The only thing I couldn't seem to get it to connect to was a splitter to be able to charge my phone though the projector and be able to use it to stream at the same time without having to mirror my phone but connect directly into my phone .
You can hear the fan a little bit with projector but that is expected with most everything when it comes to it. I just make sure there is enough air flow around it on all sides and nothing is blocking it so that it is cool. The speaker on the projector is okay. Mainly why I took one star off but it does have the ability to blue tooth. So when I want to watch an action movie or something that I want the sound to be basically movie theater loud almost I will either hook into my wireless speaker, or head phones if am watching it late at night.
I like the fact you can change the contrast and the density with the colors. This allows you to customize what you are using it for. I mainly use it for movies an shows so I keep it on the theater setting gives me the best viewing for that. You also can adjust the zoom for the size of screen you want it to project to which you can see it adjusting while doing so its not a guessing game on the size you are picking. It allows you to fit it to what you are projecting on. You also can pick what type of screen you are projecting such at full, wide, 16:1 etc.
I did hook a roku into it. That wasn't hard to do. The only thing that I had to figure out was when it asked you to pick what brand you were using to control the power and volume. I had to google that. I think I just randomly selected tell it let me move on from that part but once it did basically did the rest for me with the set up.
Over all good projector. Cost is good. The speaker could be better. Knowing what to pick for roku or streaming sticks would be nice.
Don't get me wrong, it's dim and blurry and the colors are meh compared to a TV or quality projector, but.... For $80 and some fan noise, if you've got a dark room, you can watch 1080p or less quality stuff of a giant screen.
Happrun has a newer model the J7 Pro, this one was only a few dollars more and resolved the issues i had with the h1 and it is better in every way.
It’s easy to set up on a tripod and the Bluetooth functionality works well with my receiver, albeit with a very small audio delay. It doesn't get bright enough for normal daytime usage, but works fine for dark-room movie nights.
It punches above its weight at its small size and price. I’m sure it’ll be a regular highlight of our family movie nights and camping trips.
Edit 7/14/25: We’ve been using this projector for our movie nights for a few weeks now and I still feel the same way I did in the rest of my review, however, I’m deducting one star for a minor recurring issue. The projector doesn’t have a very good dust filter so it is quite prone to debris getting inside the chassis and showing up on the image as black or white spots. You can open the unit from the bottom (under the sticker) and clean, but you must be very careful when doing this to not make the problem worse.
This might not really be a con, but the speaker is about what most projector speakers are; meaning that it's not particularly high output but handles indoor fine. The edges of the picture are not as crisp as the middle, especially the more severe the keystone correction is. The hum of the projector is a little higher pitched than some other projectors I've had, but less noticeable once you've got some audio going.
Overall it is certainly a solid projector on this price range.
It’s currently at 90 inches. This Google projector says it could go up to 300 so I’m not even using its full capacity but yeah it’s pretty kool.
I think the visual is even better in person But I’m making my wife a “house gym”in the garage, I think it will do its job.
The one thing I do not like is the brightness of the projector. I’ve seen other brands that gets a brighter or at least give you the option to do so.
Previous review:
I really liked it until this! Sneeze looking noise on inside of screen!
Worked great for a few weeks, then one night, turned it on and saw all this cloudy noise, creating shadows on everything! I checked the lens, clean on the outside but then I shined a light inside (projector turned off) and could see it was on the inside! Also inside looked like it was wet, covered in slime, I don't know what happened but up until this weird situation I really enjoyed it. Couldn't find a way to contact mfr. Through Amazon. Tried the options Amazon gave me through the app and website.
Only ever cleaned the outside lens with eyeglass cleaning fabric.
Great color, reads mkv files off flash drive. Great improvement over previous projector in this price range( previous projectors sound went bad, but it did have two HDMI, this one only has 1)
