Customer Ratings & Reviews

Pros: Very easy to set-up and operate. The image quality is good and the built-in speaker is nice to have when using as a portable device. HDMI inputs work well with Roku streaming stick and video games. Cons: (I admit I should have read the description more thoroughly) 1: The is no zoom function so the only way to adjust the size of the projection image is to physically move the projector closer or further from the screen. This is very limiting for home use, since the location of the projector will be locked depending on your available screen size. 2: There are no adjustments for leveling or angle. If the projector is not sitting on a surface, centered vertically on the screen, you will need to use a tripod or create some sort of angled platform to support the projector (set the front on a stack of books?) 3: Keystone correction works OK. The projector needs to be perfectly square with the screen surface but if the angle is more than +/- 20 degrees, it does not completely square the image.

What are the differences and is it worth the extra money for M631?
