Works with a lot of iOS apps
on October 23, 2012
Before this 3M projector arrived, I had two main concerns:
1) Would it be bright enough?
2) Which iPhone apps are compatible?
Here is what I found:
1) The brightness is quite good. 3M's own specs say this has a brightness of "up to ANSI 35 lumens" (from 3M's own specs). Though this may sound rather low, I found that this projects photos, videos, and text very well when used as recommended. "as recommended" means a diagonal of 10 inches to 60 inches. Clearly, this is a "hobby" type of device. Don't plan a professional business presentation with this projector. Keep your expectations reasonable. In a dimly lit room, with your iPhone projecting on a wall 10 feet away, images and text look good.
2) I was afraid that this device would be limited to Apple's own video and photo apps and nothing more. I was happy to find that it worked with quite a few of my go-to apps. But, there are some apps which did NOT work with this projector. So, here are some specifics you might care about (and note that what works may depend on which version of iOS you are running, as well as which version of each app you are running):
* Netflix: works under both iOS 5.1 and iOS 6
* Hulu Plus: works under both (however, I needed to update the app...an older version of Hulu Plus didn't work)
* YouTube: works under iOS 5.1, but NOT under iOS6 (probably due to the fact that Apple kicked YouTube out of its built-in apps, and the downloadable YouTube app does NOT project)
* Apple's official Photos and Videos apps: work under both (note that the photo app only works in "slideshow" mode, meaning you can't swipe through your pictures...you'll be at the mercy of the slideshow timer)
* KeyNote: works under both
3M's spec sheet says that this device is for iOS 4 and iOS 5. However, I have had no trouble using this with iOS 6.
There are other reasons to recommend this:
* I like that the sleeve can be used as a charger for my iPhone. In other words, when I don't need to use it as a projector, it can serve as a backup charger instead. Note that it cannot be used as both a projector and a charger simultaneously. It's one or the other.
* There is a button that allows me to switch among projection modes: a mode for brighter video, a mode for sharper contrast when viewing text, and a mode for preserving battery life by dimming the screen. 3M says this will last for 100 minutes of projecting before needing to be charged. Though I haven't tested it, I would assume this means "100 minutes when using the mode that preserves the battery".
* The sleeve holds the phone securely: Once the phone is slid into the sleeve, there is an edge around the sleeve that securely holds the phone in place. It takes a fair amount of effort to remove the phone. In other words, once the phone is in the sleeve, you don't have to worry about it sliding out or falling out, regardless of how you hold it. Keep in mind that this is NOT meant to be a protective sleeve. I would only leave it in the sleeve when you want to use it as a charger or a projector.
All in all, this is a decent projector for the price. It works with the apps I care about (though not YouTube, but for me that's not a deal breaker). Interested in showing a video or photos to a small group of people? This might be just what you're looking for.
