Great Little Portable Projector
I have experience with at least 3-4 projectors but I would say this projector is far better in terms of picture quality than others I had. We have been using this projector for a while in our living room and it works great. It has got bright and vivid image quality with decent sound with inbuilt speakers. Bluetooth connectivity is helpful as i was able to connect with Bluetooth headset. It’s super simple to set up, if you can’t figure it out on your own which you should be able to, there are very simple instructions that come with it. And the mirror problem has nothing to do with the projector that’s an issue with the phone/tablet. Most of the phone companies put restrictions on mirroring that doesn’t allow you to mirror on projectors.

Delightfully good.
Once out of the box and plugged in, I jumped to do a side by side with my Epson. Image was easy on the eyes, frame rate was good while watching the latest episode of Halo. Image quality was an 8/10, but I use a bare wall, so the image quality can only get better with a proper screen. The speaker is adequate, but we love our external speaker, so that’s no problem. Menu interface was easy to navigate and screen setup was intuitive. I recommend using a heavy tripod or projector specific stand to get a level and proper tilt if projecting upward. Screen measured at a diagonal 50” with projector set at 6.5’ from the wall. It’s a handsome design and a great, affordable first projector. This will need a dark or dim viewing area.

Small and powerful
When looking for a projector to replace my old one i stumbled on this one and when i got it I was shocked at how small and power it was. This small machine performed better than my $200 projector and it was half the size. Another great thing i loved about this projector was that there was no noise coming from the fans. Usually i would have to raise the volume a lot so i don’t have to hear the fan but not with this projector. Also, even without a projector screen it is able to give me beautiful colors and the movies show up so clearly. It feels like i’m in a movie theater whenever i use this little machine and because it’s so small i can take it from room to room and play whatever i want. Definitely recommend using one of these with a fire stick as well.

Not what i was hoping for
I am sure this projector is very nice. From what I have seen it has a great picture and you can adjust the angles and everything else to make sure it fits anything! BUT... I'm sure I just didn't read it enough or don't understand but I cannot get it work right with my iPhone! I thought this one would be the one to work with apple devices since you can hook up multiple ways but that's not the case. It was very annoying, and we are still considering returning it.

not disappointed, I'm very happy as I expected
I picked up this projector and hung my picture on the wall. When the projector was away from the wall, I was able to get about 80 inches of pictures. A nice feature of this projector is the way it connects to the equipment. You can use a cable, an existing WiFi network or connect directly to the projector WiFi. I've done all three, and they're easy. You can choose how the image is displayed based on the orientation of the projector, upside down, the back screen is backward, and so on. When the focus and Keystone adjustments are done, the picture quality is excellent. The darker the room, the brighter the colors. Projecting my smartphone is a simple application, and the projection of my DVD player is plug and play. The sound from this compact projector is amazing - enough for movies and PowerPoint presentations!

Fantastic portable unit
Finally got a chance to try it over the long weekend and it is actually pretty good. Picture quality-wise, it is definitely good for such a small unit and if you have a separate screen to go with it, it’s even better. ( Forgot to take pictures, uhh). Relatively quiet, and it works with my Mac or my iPhone. Thanks for the HDMI cable though. Funny how you can take of photo of your projected iPhone which is taking a photo! Overall, the build quality is good. The strap is made of leather and the design is cool.

Don’t buy!!!
I bought this brand new. Looked super nice and seemed to work well. The issue with this is that everything lags. I used my iPhone and laptop and the voices were lagging with the mouth movements. ALSO, it NEVER actually allowed me to play a movie. There was always and issue with it telling me to restart the application or it would almost play but never load or would stay frozen. The whole point is to be able to watch movies on it and watch them with ease and it couldn’t even do that. I’m definitely irritated lmao.

If it was over $100, I would consider it being "average pricing", but during blackfriday, the price dropped to 70~80; best purchase ever. Quality is average, leather handle made it look somewhat luxurious, but buttons and remote had low quality feel to it. Projection was average, but you definetly need the remote when setting it, as focus was way off for me to do anything to adjust anything. Little bit careless it seemed. Functionality, the more you know how hdmi works, the better you will be able to utilize, for me, I am using my smartphone to project, which is pretty much all I need. Overall, an amazing purchase, if you compare it to high quality projectors costing 1k, the only difference I noticed was the noise level being noisier than the described level.

I bought this to replace a pocket projector, but this is much bigger, cannot download movies, has no streaming software, and does not work without being plugged in. You plug it in, turn it on, and give it something to project. Basic. However, it is 1/4 the price of everything else I looked at, it is quieter, brighter, sturdier, and it works just fine with a Roku stick. I haven't tried casting yet (which our pocket projector couldn't do), but according to the other reviews, I expect it will work fine. It would be great if we could charge it and download onto it, but it works great and we are very happy with it. Good value for the the money.

I was looking to upgrade my old projector because my old projector only supports a 2.5g band. I bought this projector after reading the description and I must say I am very happy with my purchase. I got a 2.4/5 G supported projector with high resolution and a comparatively decent price. The best thing I love about this is its portable handle. I can carry it anywhere Indoor and outdoor. I put it on my bedside and the side projection helps me to get the perfect frame. No extra noise and better sound quality make it a perfect choice for a small living space. I connect it with my Bluetooth soundbar and literally enjoy a personal theater experience. Though I didn't use the projector screen still the pictures look great. Definitely recommended this projector if you are looking for the best projector at this price range.

This review is not to say if you should or not buy but to consider the following facts not clear about the product: A) You need internet to use for basically everything. The only way of using without internet is to download movies and use the HDMI cable. B) The saying about “use your phone” is to mirror your phone. This is just mirroring function to share with the projector. However, Netflix/Prime doesn’t allow you to reproduce a movie with the mirror function on, even for a downloaded movie. So, not sure for what else this mirror function can be used honestly. C) You cannot connect to the projector as an advise hardware. Meaning, you will need to plug in a Google chrome for instance (or any other receptor) to be able to connect your movie app, similar to what you do to watch on the TV. But remember, for all this you will need internet. To summarize, if you’re planing to use where you have internet, it’s a good project for a basic projector, considering price and quality. But remember, the connection with the phone is a mirror connection and most of the movie apps don’t let you show a movie with this function on. You will need a receptor as a Google chrome to plug in the project, plus must have internet for all this as mentioned many times on this review. The only exception is for A) above!

When I open up the box, there’s very strong cheap plastic smell. Whole projector feel cheap, not worth the money. Brightness is ok. Resolution is never 1080p, advertised as 720p (1080p). Not recommended.
