Review on Nic pow Native 1080P Outdoor Movie Projector - 7200L&8000:1 Home Theater Projector with ±40° Keystone Correction. Compatible with TV Stick, PS4, 2HDMI, VGA, AV, and 2 USB Ports by Chris Cervantes

I bought this projector specifically because I need horizontal keystone correction. The projector needed to be mounted off-center on the projection screen, so in addition to the vertical keystone distortion that most projectors have, I also needed to be able to adjust the left-to-right keystone distortion. In the photos of this item, the seller clearly states that it has a +- 40 degree horizontal keystone correction. However, upon receipt of the goods, the instruction manual clearly stated that the correction was only vertical. I am very disappointed as I can no longer use this projector. It also arrived 3 days late.
