Hi, i have here for sale a Optoma EH412STX. This projector is a open box item that is in mint condition. I just removed it from the sealed bag for testing only. This has a total of 1 hour and the lamp security sticker is intact. The projector  produces a beautiful, very bright image and works perfectly as it should. This model can be easily used for home theater, presentations, golf simulation etc. This particular unit has excellent focus uniformity, its nice and sharp across the whole image. This does not have a soft/uneven focus which very common for these Optoma short throw projectors. I uploaded several images to show you how nice the image is. This sale includes the projector, remote and the power cord. I don't have the original box but will be carefully box this item up. This will ship fully insured in a new Ebay shipping box. 

From Optoma —  Project bright, vibrant presentations effortlessly in Full HD 1080p any time of day. Designed for small meeting rooms and classrooms, this short throw projector boasts amazing color, long lamp life, and energy-saving features to provide a lower overall cost of ownership. Multiple inputs, USB power, and a built-in speaker provide an easy set-up - perfect for connecting a laptop, PC, or Blu-ray player for clear projected images with sound. You can even use the USB power to connect and power HDMI dongles such as Google Chromecast.
