Review on WiMiUS P18 2021 Upgrade LED Movie Projector Native 1080P 4K Compatible with WiFi Dongle Bluetooth Transmitter, Amazon Fire TV Stick, Laptop, iPhone, Android, Xbox, PS4 Via HDMI USB VGA AV - Support for 400 Feet Projection by Mido Taylor

Ordered a projector and the first one was dead. (It just turned itself off.) Revain sent me a replacement which I've been testing for an hour now so this is a preliminary review. Order this projector if you don't need a manual. For example, you need to open the remote control and insert two AAA batteries (not included). The projector has many features; Too bad they are not in the manual. It has two HDMI inputs, two USB inputs and a composite video signal. I tested an HDMI port and a USB port. With USB I was able to play MP4 movies, MP3 audio and JPG. Revain's websites state "3 YEAR WARRANTY AND 7/24 SUPPORT: Rest assured of our quality, we promise a 3 year warranty on this upgraded projector including a 1 year money back guarantee" but the with The card supplied with the projector only mentions 2 year warranties. And customer service didn't answer the call (but Revain customer service did answer_. I love that the LED projector turns on (and off, you don't have to wait for the lamp to cool) instantly.
