I bought this because I was looking for a low-cost projector. I bought this to use for lectures and Sunday School classes, and figured I'd use it to watch movies at home too.This unit meets my minimum requirements: It works. It has a resolution high enough for any serious need. The picture is clear and crisp.You can connect it to a computer with a standard computer video cable. It also takes an HDMI cable. I have a computer with HDMI output and this worked fine too. It also takes composite video that I didn't try.It has some limitations that may or may not be important to you.1. The image is not bright enough to see in a well-lit room. It looks great in a dark room. I used it in my living room with a single 100-watt bulb and it was fine. But when I tried it in a classroom with bright overhead lights it was seriously washed out.2. There's no way to adjust the size of the image other than to move the projector closer or farther from the screen.3. It has built-in speakers that have good sound quality, but not great. If you want to show a movie, say, there's no problem understanding what the actors are saying. But I wouldn't use it to music. It's not high-quality stereo. It does have hook-ups for external speakers.4. An odd one: it has no left/right leveling. You can raise or lower the front, but if your table is not level compared to your screen, you'll have to put a book under one foot or some such.I've only had it for a few weeks so I can't say anything about durability or bulb life.
