I got the projector today, and immediately got down to playing!
Unfortunately, it wasn't quite as intuitive to use as I would have thought, thought pretty simple to figure out (especially after reading the directions). Anyway, it's decently bright, and will be just fine for the night time.
It was day when I started playing, but we went into the basement and shut the blinds, so it was fairly dark. This is with the lights off, projected from about 8 feet away, resulting in an image that was about 5 feet across. At that range, you start to get a bit of the screen door effect (where, if you look closely, it almost looks like you're looking through a screen door, because you can see the pixel grid, or whatever), but it's not bad at all, and, through a screen and window, with all the other stuff going on around, it will be just fine.
This is with the lights on, which included a regular recessed light nearly directly above it.
Anyway, it's super simple to use once you poke around for few minutes. For example, after inserting the SD card with the videos, they appeared to be empty. It just took a minute or so to actually load them up, but once they were there, they were fine. Then, I clicked one to watch it, but it just popped up in an odd little window that still had the blue background behind it.
Turns out (as the instructions plainly state), you just put a checkmark by the ones you want to play, then hit the actual play button. Who knew?!
The construction seems pretty decent, although the fan was a tad loud at times. The keystoning worked like a dream, and focus was a breeze too. It also has an attached rubber lens cap, and a three or so foot long power cord with a two-pronged adapter. I ran it plugged upside down while first trying it, but the adapter got really warm. The internal speaker is decent enough for light sound, but only if you're near the projector itself. I doubt I'll need the sound much (except, perhaps, for the Christmas ones), but there is a regular earphone jack. It also flips the picture at the push of a button, between front and rear projection, both regular and upside down. The SD card also comes with both horizontal and vertical videos, and it apparently plays several different formats.
Anyway, since it's getting dark now, I'm going to play some more. But, for anyone interested, the instructions, including some specs are below.
Cheers!
