Review on Bluetooth Projector WiMiUS K1 Smartphones by Patrick Arnautov

I'm very happy with this projector: I like the four-point keystone correction, which allows me to place the projector in a corner of a room and project a good image after correcting every corner of the image. The picture quality is quite good and it's bright, especially when the room is dark. But it also works pretty well, even with the lights on, which I use when I want to exercise, so it's perfect for that kind of light-on use. The sound is better than I expected, although it would certainly be better if you connected a Bluetooth speaker. I haven't tried wifi or bluetooth. I only use an HDMI cable. The remote works fine even when I point it at the wall. You can hear the fan, but forget it once you're immersed in a movie or whatever you're watching. Note that the zoom only works when using lateral keystone correction, as opposed to four-point keystone correction. But you can reduce the screen size, use the four corners to adjust the size. (The first attached image is not rectangular due to the angle I took it from my phone while watching a movie.) So overall I'm very happy with this projector. It's also quite small and comes with a pouch.
