Review on 🎥 WiMiUS Upgrade K3: 4K 5G WiFi Projector with 340 ANSI Lumens for Indoor/Outdoor Movie & Home Theater - Native 1920x1080 LED Display & 500" Zoom Support by David Ross

Overall the projector is good. Some things to consider. If it's too close to a wall, it will be very blurry. The edges are also a little blurry, unless that's the ideal distance from the screen/wall. There's no scaling, so you have little flexibility in placement if you have screen size limitations. In the evening the brightness is good. It's not very good during the day unless it's very close to the wall. The volume is pretty good, but you can't control it from the projector. So be sure to have a remote control handy. If the sound doesn't work, go into your sound settings and disable "Dolby" digital audio and it should work. It works with the firestick, but some things cannot be controlled with the firestick remote. So get ready. In general, everything works well and does its job.
