If you have reasonable expectations you will be very happy with this. This is NOT a replacement for a quality home theater projector. A great inexpensive device to use occasionally e.g. It's smaller than most projectors, about the size of a dictionary and weighs about a pound. The device is brighter than I expected, but you need a dark environment. If you cannot darken the surroundings, scale down the image. The colors are bright. The movements are smooth and natural. I plugged in a FireStick, the audio can be surprisingly loud but has a flat alarm tone. No problem to listen to news or sports games. You can connect a portable speaker or soundbar if you want to enhance the sound. The fan is a bit noisy, but don't put it near it. For me it is not a decisive factor. It could be used for PowerPoint if the font was a decent size. Don't expect to see Excel spreadsheets unless you zoom in. To get good sharpness, make sure the device is mounted horizontally and parallel to the wall it is projecting onto. While you can tilt the device and use keystone correction, I found that only the center of the image is sharp and the corners aren't as sharp. The best way I've found is to focus on the center and then adjust with the trapezoid wheel until the angle is sharp. Please note that there is a focus area and it is well adjusted to the size of the wall. If you try to take a 20ft picture, you can't get it in focus. Includes 12 volt 3.5 A power pack. Two AAA batteries are required for the remote control (not included). Inputs: Two HDMI, Computer, Flash Drive, MicroSD. Output: headphones and audio. Metal tripod socket with thread on the underside. I have already ordered another one as a gift. I think you will be very happy with it if you have reasonable expectations.
