Review on WiMiUS 4K LED Video Projector: 200'' Display, 4D ±50° Keystone Correction, 50% Zoom - Ideal for Indoor and Outdoor Movies, TV Stick, PC, Smartphone Compatibility by Roberto Manzer

Beamer got and started immediately. Unpacked, it is fully functional and will be delivered well packaged. The projector has been in use for about 2 weeks. I didn't use the remote control, but used the buttons on the projector to change input modes, check menu items, and change volume. It's a little tricky to use the buttons, but you'll learn quickly. The built-in speaker is loud and even decent at 50% volume. The buttons at the top with side arrows help you change the volume. I hooked up a small portable speaker and needed to change the sound source to line. You can rotate the lens to fix the focus of the image. The board has not been used for anything. It will give you very bright images even in low light. And with the introduction of new software, 1080P 30Hz video playback no longer causes output lag. The size, color and clarity of the images are amazing. There is no blur at the edges. We've watched quite a few movie nights and the picture quality in a dark room or at night is amazing. I also tried the MK11 on a switch connected to this projector and was blown away by the screen clarity and lack of lag. It comes with the best cooling system, the heat generated can be dissipated in a timely manner. Thus, the lamp can last about 150,000 hours, which is twice that of other LED projectors. Good that the guarantee is 3 years.
