Summary: We used this remote for Worship Service. The stage is 2 ft off the ground, and around 70 feet with no obsticals in the way to the PC which is elevated 5 ft in the air. The operation was very intermittent even with fresh batteries.
works well throughout our auditorium. would be better if it could be used as a mouse as well.

Summary: this pointer works from over 50 feet away, throughout our auditorium. it is very good for clicking through a powerpoint presentation. It would be even better if it could be used as a mouse, and not just a pointer.
Summary: I bought this for church where the computer that controls the slides is upstairs and across the sanctuary. I knew that folks would point at the slides - a 90+ degree angle from the computer. It works great!
