Customers have mixed opinions about the sound quality of the video projector. Some say the image and sound are impressive, while others mention the speakers are not that much better, the volume is better, and the fan always on has a slight hum. The built-in speakers could use work, but they are still pretty loud. It frequently lags and has out of sync audio, making it frequently unwatchable for Hulu and essentially useless as an AirPlay projector.

Stellar performance in a tiny package
I’m really happy with this. The picture quality is great. We got a 150-foot screen to test its limits and it fills it up beautifully, from corner to corner of crisp, clear picture (when my WiFi is at its best, anyway.) I’m an Apple TV user, so I had to get used to the new interface and remote control, but they’re intuitive and easy to navigate. People complain about the battery life, but we haven’t had an issue there. We just set up the projector near an outlet (or use a big ol extension cord). I also love the compact size — it resembles a cute little lunch box, so it packs away so easily when we’re through.

    I bought this projector to replace an old one that required so many connections to a laptop. This has been the best decision I ever made. The projector is lightweight and small enough to be stored anywhere. It comes fully loaded with many apps and all you need to do is connect it to your wifi. I use it with a 130" screen and the picture is perfectly clear. One of the best parts of this projector is its self-leveling and self-focus. It does all the work for you. The best purchase I ever made.

    I was sort of worried this product was not going to exceed my expectations, but it did more than that. All apps are imbedded in there, Hulu, Netflix, Disney Plus, Youtube and you can download any other app. I wish the battery life can be longer, but it gives you angood 2 hrs and 30 minutes which is plenty of time for a movie, after that you would need to plug it into an outlet. The image quality is amazing, it looks very clear when it is dark and when there’s light it’s a little hard to see but you can still see the image well. The color itself is vibrant and the contrast and hues are all on point. It comes with its own remote and the product is very easy to use, it is like using a smart tv just on a projector. It is very durable like i said 2hrs and 30 min before plugging in. Built in speakers could use work but they are still pretty loud. Overall amazing projector.

    An Awesome Projector for $500

    Reviewed in the United States on December 25, 2023

    Verified Purchase

    I don’t usually write product reviews, but since this is a new product with only a few short reviews, I’d thought I’d write one for the people curious about this projector.

    Picture Quality/Size- The 1080p picture looks great, the picture doesn’t look too over saturated and I found that I can project images over 200” in a darker environment, well above the 150” stated on the product page. This projector CAN’T handle bright environments, it CAN handle late afternoon to night time viewing.

    Software- Built in Google TV is GREAT. I thought I’d use my Amazon fire stick with it, but Google TV works well. The OS is responsive and has all the usual apps, even native Netflix support. Most other projectors need a work-around to install Netflix. Auto keystone is pretty good, it’s fast and reliable. I sometimes need to fine tune the picture slightly but I’m OK with that.

    Built in Battery- It’s good I guess. Not much to say. I found to get just over 2hrs of battery life. I did seem to notice the battery drain a bit even when turned off.

    Speakers- The speakers are GREAT. It gets pretty loud but the quality stays clear. I have two Bluetooth speakers I’d thought I’d use with it, but there’s no need, the internal speakers work great. Now it’s not a home theatre system, but it works good for built-in speakers.

    Fan- The fan is always on and has a slight hum, but if you turn the speakers above a whisper, they drown out the fan noise.

    Remote- it’s good, not much else to say. Hot buttons to Amazon Prime and Netflix are nice, as well as the auto keystone button. The projector has buttons on itself as well, in case you don’t want to use the remote.

    Great OS + great picture/size + great speakers = Great portable projector. Overall I’m very happy with this projector and I think anyone who’s looking for a portable projector will be too.

    Ok lag is def an issue with this software. We have to clear cache every time. It’s def annoying and inhibits enjoyment. Wish I could return for better projector. You need 2000 lumens to watch during summer. We def had some enjoyment out of it, but the other night was cringing to me to see how much it would buffer. I have Gb Ethernet and strong wireless too.

    -previous posts-
    This is about 12’ away one pic with ambient lighting (Christmas Tree and lamp), and one with less ambient lighting (backroom light)… projecting nearly 100” wide… complete dark out would be even better. This was my main fear that it wouldn’t be bright enough, but as you can see it turned out great. I also watched the news a bit and it too was great, and very legible text. Looking forward to some football on this bad boy. I do recommend a tripod of some sort… this was propped up on a stool with a book under the front…. Not sure why we don’t have a couple of front feet/flap built into this unit. So All in all, so far so good! I did find using app was better on the native device vs streaming from phone( slight lag there but could have been my network) Some Apple TV app issues trying to work through also but hard to do while “elfing” around (Christmas Gift) after kids are asleep. Oh and expect an update after first opening. I’d get it out of the way before movie night. 😉 hope this helps! More to come after Christmas.

    Ok found the Bluetooth settings deep into settings and then settings again…lol after pairing with home theater receiver via Bluetooth this thing will 100% be movie theater at home 🙂

    Had to use 100% speaker volume in large living room (movie mode) prior to this. Would likely be better in bedroom.

    Brightness has been a bit of an issue outside of sports and cartoons, really what you’re buying on this is portability. But if you have a tripod and power and Bluetooth speakers, you could argue that portability might not matter unless you’re going room to room with this or traveling.
    -update-
    Ok summer time is a no go for this projector at 100”+ , you’re going to need like 2000 lumens to get a movie in at 8pm – peak summer hours. Still used once dark 9-9:30pm…I still like it, although there may be some others that can beat the lumens and Netflix integration around the same price.

    Excellent Projector for the price

    Reviewed in Canada on January 4, 2025

    Verified Purchase

    I originally ordered the much more expensive Cosmo 4K SE, which also was an excellent projector, but was much larger and was slightly overkill for the use I wanted a projector for and it didn't have a battery which was a shame.

    So I ordered this one, which I was already interested in, it might be a 1080P projectors but I am more then happy with the visual quality of the projector, the size to distance ratio is perfect, to project onto a wall in the basement to watch some movies or shows with my GF, we are not using it to the full size it can do but I have test that to and it was more the clear to me. As for the brightness of it, I will say it could be brighter but it's still more enough to watch with a light on or two without it being drowned out. The size of it is absolutely perfect for me, I bought a cheaper stand which make it look smaller, out the size with the fact it has a battery, it makes it super easy to just move around and store it away unlike the Cosmo I originally had. Which with how good the auto focus and keystoning is, I never had an issue where I had to fiddle with the settings or placements. Even the speaker were surprisingly good, the volume can fluctuat from loud to quiet and back but that is more on the content I was watching then the actual speakers themselves.

    Over all for the price I paid for it and what I got for it, I would say it's absolutely worth it with plenty of value to it.

    Fantastic Projector – Bright Compact and Perfect for Any Occasion

    Reviewed in Canada on January 23, 2025

    Verified Purchase

    I bought this as a gift for my loved one for Christmas 2024 and this projector has been absolutely fantastic so far. I’m blown away by how bright it is!

    Picture Quality: The picture is bright, sharp, and detailed with natural-looking colors. It’s everything you’d want in a projector.

    Appearance: It’s small and lightweight, making it perfect for a nightstand. The top grip makes it super easy to move securely from one place to another.

    Audio: The audio is phenomenal! The speakers deliver impressive sound with deep bass, clear highs, and plenty of volume. Even at low volume, the sound is rich, which is great if you don’t want to disturb someone in the next room.

    Technical: The fan noise is practically non-existent, which is a big plus.

    What I love most about this projector is how social it feels. Thanks to its top handle, it’s so easy to carry around the house, and it fits perfectly into any situation. It brings people together with its wide image and built-in streaming platforms—your friends can pick whatever they want on YouTube.

    Highly recommended for anyone looking for a versatile and fun projector!

    Could be the best portable projector ..missed the mark by few points

    Reviewed in Canada on February 24, 2024

    Verified Purchase

    The image quality of this projector is amazing. Despite its not 4K , I have tried playing 4K video files and it looks amazing but only under certain conditions. Sound is also amazing. No complains there. Portability is also amazing. But then comes the flaws –
    1.Image quality suffers once you place the projector farther than 6-7 ft from the screen. It gets dimmer and less sharp. I would wait for the next version of this hopefully they make it slightly higher resolution and 4K supported
    2. Dark scenes gets washed out a bit with darker parts losing details even at close range viewing.
    3. The power chord is too short for me. I want to watch movies in my bed but accessing power outlet becomes a problem.
    4. 2.5 hours of battery life is really short. You have to plug it after that.
    5. The Adapter gets really really hot. So hot that you can crack an egg and make an omelet on it. Jokes apart , it can be a hazardous for kids if they touch it while plugged into the device. Please fix this.
    6. Lastly there is no lens cover. I wish they add one to save it from dust.
