I bought this in October of 2023. I'm a smoker and never once thought about what might happen to a projector while I literally SIT RIGHT UNDER IT and smoke. Needless to say, the image was getting dimmer slowly, and I chalked it up to being cheap. A little longer of this and I finally realized it was ME ruining my projector. I tried cleaning it, taking it apart, but chickened out when it looked to difficult to come back from if I made a mistake. I ordered a YezMek brand cause I thought electronic focus and tilt would be "neat". The first projector from them had a blue rectangle in the center of the screen about two days after the warranty ended. They sent me a new one anyway and up until last week it was fine. It's getting the blue rectangle. And that electronic tilt? I watched a YouTube video about projectors and that electric tilt reduces resolution! The mirrored tilt is better, which THIS projecter, the one I killed had. I still have it, I might try and clean it again, but as soon as bills let up a bit, I'm absolutely buying another one of the Happrun projectors. It was wonderful.

This Happrun projector is worth every penny. My last projector cost 4x as much and was only about 1/4 better in quality -- if that.Image quality is about the same, with the happrun actually beating out my old one considerably in noise reduction and sharpness settings. The haprun has better sharpness at the edges when I get it set up just right (see below,) but the top left and bottom left corners are still a little soft after doing everything I could to ensure a good setup. (Not a deal breaker for me.)The fan on this happrun is half as loud as my old one, which is great.The little hatch you can open on the bottom of the unit to easily clean the lens and screen is wonderful! I had to disassemble my old one to clean it, which meant there were often dust spots on our movie screen because it was such pita to maintain the machine. All projectors should be this easy to clean.The lightweight design is great. Not only is it portable, the standard tripod screw hole in the bottom makes it possible to just stick this on any tripod or light stand for quick setup and takedown.The speaker is actually loud enough to overpower the fan. I'll never use it because I use a soundbar or headphones. The speaker is tiny and sounds hollow but it'll work in a pinch of you need it.I only use HDMI so I can't speak to other connectivity features of the device.The one area this projector lacks in comparison to my old one is the keystoning feature. My old one offered four point digital keystone correction, while this haprun only features vertical keystone by means of a wheel. Yeah, you can use the wheel to square up your image if you can't get the projector level with your screen but I don't recommend it if you actually want to enjoy what this projector can offer. Any slight adjustment of the keystone wheel will make everything go out of focus from the center of the image to the bottom or top edge, depending on whether you're adjusting the top or bottom with the keystone. You absolute MUST get the projector level with your screen left to right because there is no horizontal keystone.If you move the keystone wheel, you may find yourself having a devil of a time getting your image in focus again because there's no markings printed on the machine to tell you where to return the keystone wheel exactly to center. I got mine as close to perfection as possible by adjusting the focusing wheel until the edge of the image that was NOT altered by the keystone wheel was as sharp as I could get it. Then I adjusted the keystone wheel until the opposing edge of the image was in equal focus. On my copy, doing this resulted in a sharp center as well. Once the image was in focus corner to corner, I just angled the body of the actual projector to straighten the image on the wall, ignoring the keystone altogether.To enjoy this projector most, you're gonna want to avoid using the keystone at all, which means you've got to have the projector perfectly level with the surface you project it on. I already owned a good tripod with a ball head mount that allows me to position the projector however I need to. If you don't have something to set it on or a way to mount it, you might not enjoy the image quality as much.All in all, I'm very happy with this purchase! If you're on a budget this is a perfectly acceptable TV replacement for watching movies or cinematic shows that deserve a big screen. At this price, you really can't go wrong. You just need a way to mount it and a little knowledge on how to set it up to get the most out of it.Oh, also, I went over to YouTube and used "projector test patterns," to get mine into focus and to help me adjust the color, brightness, and contrast. I highly recommend using those. It'll make your setup process way easier and give you a better looking image.

I've used a lot of projectors over the years and this one is a great projector for the price range. I particularly like how easy the setup is. HDMI with another source (like a computer) gives you instant use, or take a couple minutes to log in to several apps like GoogleTV, Netflix, or Amazon Prime that a pre-installed. The picture quality and luminance is right in line with other projectors in this range. The focus wheel is conveniently placed. I absolutely love that the keystone correction is also a convenient wheel right next to the focus wheel. Another thing I absolutely love about this projector is the size (8x10x3.5 inches) which is smaller than most.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.
