Summary: I used to install the big CRT and DLP projectors, some were hit and miss and still cost thousands... This hit it out of the ball park and I was truly expecting a bunt at best. Now don't expect to watch anywhere other than a nice dark spot with external speakers, or headphones, if you want to enjoy it. And it is not HD, but If I compare it the picture on most TVs that are not HD, it can rival most SD TV pictures I have ever seen.
Summary: I connect this to an 80GB iPod Gen3, and my son can watch endless movies anywhere he wants. The internal speaker is a bit weak, but add some headphones or plug into external speakers, and you're good to go. The battery life is better than I expected, and the picture quality is quite good. The build quality is solid, and I don't have any fears of my 6 year old breaking it as he takes it places.
Summary: Sure you may be able to find something better, but not for the money. This little beauty is wonderful, and tiny. It has one single drawback, which there is no way they could do better, it would be nice if it were just a tad brighter. I am not saying you have a problem seeing the images, just would be nice if it were just a tad brighter.
Summary: This is a great product. Keep in mind, you aren't spending much, but it's well worth the money. I thought I was getting ripped off when I opened the box because it was so small, but I was very glad to be proven wrong. As others stated, it does need to be mostly dark to work well, but since I was getting it to watch movies and play games (Wii) I prefer it mostly dark. The speaker that is built in does suck...
Summary: Although this projector may not deserve five stars because it is far from perfect, I am giving it five stars because it more than exceeded my expectations for such an incredibly low price. And they include an extra battery to boot. First let me say that I had a very bad experience with the Microvision projector which cost over two hundred dollars more than this projector. The only advantage of the Microvision is that it does not require focusing.
Summary: I bought this projected through an auction site hoping to resell it on Amazon. I took it out of the box to try it out and was so impressed that I'm definitely going to keep it! The iPhone integration is AMAZING! just plug in the dock connector and you can play movies from a variety of different applications.
