3M MP225a Pico Projector Review
A deplorably designed pico projector.
Picos tend to be quiet little guys, the MP225A was no exception. An increase of about 12 dB is not very loud, but consider the speaker power you will be using to show your content. If it is coming from the iPhone, you may want some external speakers to be able to hear the whole story.
We measured the exhaust fan as putting out a little more than a 20º F increase in temperature. Compared to their larger video projector counterparts, these pico projectors do not get that hot and can be placed anywhere.
If you used this projector as frequently as you would a home theater setup for a year, it would cost you $2.47. You will probably still have a TV or some other way of watching content at home, so you will not even be using the 3M MP225A even that much. We don't know if you can fit this into your annual budget. You may have to stop using heat and water all together.
The 3M MP225A uses long lasting LED lights to give users over 20,000 hours according to the specs sheet. These lamps cannot be replaced, so after 20,000 hours, you will have to properly dispose of this pico. If you think about 20,000 hours being more than two years of watching without ever turning this projector off, you should be okay.
