There's no lens shift or zoom.
The speakers sound ok, but can be a little piercing at high volume.
There are single HDMI and USB inputs.
There are a few controls on top, but if you lose the remote downloading Anker's app is a better idea.
Usually hidden, there's a small USB-powered streaming box in the back.
The remote requires setup, and can be forgotten by the projector, leaving you without control.
