"You can also use the M1+ as a high-quality Bluetooth speaker. The dual internal speakers put out three watts of sound power, which, at the highest volume level, easily fills a nice-size room."
IT World Canada Review
"Because the M1+ are likely to be used closer to the projection surface, it has a higher throw ratio of 1.2. Combined with a 3m usable distance, it can produce a projection up to 3.6m wide. Impressive for such a tiny unit."
Lifewire Review
"After reviewing a handful of projectors, I've decided the ViewSonic M1+ Portable Projector is the best value yet. Weighing in at two pounds, it offers a robust speaker system (a feature that's so consistently lacking in other portable projectors), crisp projection up to 100 inches, and a small but sturdy body, all for under $300."
Computer Times Review
"All things considered, I’d say the M1+ is a great little projector for enjoying content you either own or can cast, in any room of the house, on any surface. I especially loved being able to lay in bed and binge watch my favorite shows on my ceiling, or have a little slideshow of past vacation photos, and dream of being able to explore the world again."
What the Tech? Review
"The ViewSonic M1+ provides a better brighter picture than most projectors. It has an internal battery so you don't have to lug an extension cord out to the yard. The battery lasts about 2 and a half hours, but you can plug it into electricity for a longer movie or game. A built-in Harmon Kardon speaker is loud and clear enough on its own but you can plug in another speaker as well. It's $255 depending on where you are shopping."
ZDNet Review
"Just because you don't have a ton of cash to spend on a projector, that doesn't mean you have to skimp out on quality. The ViewSonic M1+, like its cousin the M1 Mini+, is a super-compact projector that's great for setting up at home or taking with you to a friend's house or on a camping trip. The integrated battery gives you up to 6 hours of use on a full charge, and the built-in stand makes it easy to adjust angles and throw distance. You can get up to a 100-inch screen at just 40-inches of throwing distance, so you don't need to worry about your room not being big enough. It also features dual, 3 watt, Harman/Kardon speakers for incredible, room-filling audio without the need for a separate speaker. The M1+ has a suite of pre-installed apps, including Netflix and Spotify, or you can mirror your mobile device to share TikToks and YouTube videos with friends."
