Bought this UST Projector after many months of research and could not be happier with my purchase! The image quality is amazing and I still can't believe how loud and crisp the sound is coming from this device! The set-up was very simple and the Android app makes using this very simple as well. The looks of this device are top-notch and high quality and I love the 120" imagine I have coming from this! I have an Nvidia Shield TV plugged into this and love watching all the 4k HDR streams!
