ViewSonic M1 Mini Ultra Portable LED Projector with Auto Keystone, JBL Speaker, HDMI, USB, Stream Netflix with Dongle (M1MINI)

This is an excellent bang for the buck. If you want something to play from USB storage or HDMI input on the go, travel, camper,or RV this is the unit you want. It doesn't have all the extra stuff you won't use traveling. No Wifi, no Bluetooth, and the price reflects that. The up and down auto keystone is pretty amazing you just point it at a flat surface head on and it will snap to a rectangle for you. It is plenty bright but in a very bright location it can be a bit dim. The fix for this is to move the projector closer, smaller viewing area but will be bright enough. The resolution is not fantastic but it downscales seamlessly. Do not expect this to be good for a computer workstation. Movies -> YES. But not for actual computer work. The built in media player is acceptable. It played 10gig HD mkv files with no problem from a USB hard drive. The player doesn't remember what you watched but will resume from the point you were in the last movie. I prefer Kodi and use a Raspberry PI 3 but the built in player is functional and does what it should.

I have an old projector PJD5533W with 1080P and 3500 lumens for years and now have a new protable projector M1 mini plus with 720P and 120 lumens.The 1st thing you need be careful is that the remote of mini projector is very easy to be interfered by my old projector or even the TV... I see some other user mentions that the remote malfuctions. I believe it is the interference. I have two projectors. And their remote work on each other. When these two projectors power on or in standy mode in a same time, the large projector receives all signals from two remotes, and the M1 mini plus hardly receives any signal and gives response. In this case, you have to use mobile apps or USB mouser on the mini projector to avoid remote interference. Viewsonic have to give solution on this issue.The M1 mini plus have excellent color in dark, good color under inddor lighting (brigtest of Philips Hue), acceptable in indoor half daylight. Of course with only 120 lumens, this mini projector is not recommend for full daylight or under sunshine. If you want a good color in daylight, go to buy a projector with 3500 lumens or more.For the resolution, 720P is good enough for video, presentation with large text front, or sync the ebook on mobile screen. But if you use it to project normal text from 1080p source of PC, it's hardly read.M1 miniplus can project a small screen of 13" or smaller like 10" in a short distance. Due to 720P resultion only, if the project screen is over 30", the resolution drop is significant but still good for video. When it projects a 60" screen, it's very different compare with my another 1080P projector. I prefer to go back to my old 1080P projectior in this screen size.The automatic keystone correction of M1 miniplus doesn't work all the ways. Expecially on uneven project surface, with something blocks in the middle, or in over light envirement. The problem is that when the auto keystone correction doesn't work, here's no manual keystone correction as backup...The mini projector M1 mini plus is quite hot. My old projector PJD5533W is very hot too when working.

This is a very good value for the price!1, The built in Operating system and software with apps are MUCH better than other projectors have. SIMPLE, FAST, Easy to configure or add more apps.2, JBL sound system is very clear and reasonably loud.3,Connectivity is fantasting. Bluetooth connection is fast and has no delay with external BT speakers. Phone screen mirroring is easy. Both Android and IOS connects well compatible with many apps. Can use HDMI or USB connections too4, Charging / Battery, battery lasts a full movie on full charge but can plug in to charger while you watch a movie5, Screen quality. This is very good considering this is a 480p screen, with manual focus (but at least it works flawlessly). Auto screen adjustment is incredibly good. Screen brightness is ok, not the most bright but for the size and price of this it is great. In dark rooms ir works well.6, Portability: Excellent! Fits in my pocket, lightweight, no need for tripod with the built in stance.7, Remote is easy to use, however it has an IR sensor (this is fine, again for the price) so you have to point to the unit direction.Suggestions: Make the same with 720p and brighter LED screen in the same size and weight and I will multiple!

Edit: The projector still worked with an HDMI cord and applications. Now these are things I noticed after around 5-10 hours of use:I got this projector hoping itll work wirelessly with my iphone 11 and ipad. When I got it, I noticed that the picture quality was great, brightness was also very nice even though the lights were not completely off, and the remote control worked fine. Problems arose when I tried screensharing my iphone/ipad with the projector. It did not work at all, even though I followed all the instructions.And sometimes it went back to the home screen mid-streaming a prime video or a youtube video.I ended up returning the product in hopes for finding a better one in the future.Cons:- screen mirroring does not work whatsoever with my and my friend’s iphones (iphone X and iphone 11)- the remote does not seem to work very well with amazon prime videos. Im not sure if its the app, but while watching episodes, the application crashes and brings it to the home page.- the brightness is not as bright as I hoped for, but it is decent- the battery dies very quicklyPros:- is very small and does not make much noise- size of projection is okay, and they are fairly clear (can read small subtitles etc)- good sound quality, I used bluetooth speakers, though, because its a little odd having sound come from one small spot when watching movies.I am giving this a one star because the main reason why I bought this was to screen mirror from my phone without needing a HDMI cable.
