The Epson BrightLink 436Wi is a very robust machine. The design, layout and feel of the machine is solid. Being ultra short throw you will notice the large round lens in the front. This gives it the large images from very close up. Just to the left of the lens you will notice the sensors that make the projector interactive. There is a very accessible filter on the side of the projector near the lens.
On the top of the projector you will find a door where the lamp is. Replacing the lamp is easy because if you ceiling mount the projector you will not have to take it down for servicing. The control panel is also on the top of the projector. It has a full suite of buttons for controlling all the projectors functions. Always easier to use the remote, but in a pinch, the menu system is well designed. Traversing it is very easy.
