Negative Positive
Title: inconsistent
Review: For a little while this pointer worked fine for me. It lasted through two semesters teaching one class per semester. However, once I started full-time (this past year), it was so inconsistent that I finally just had to stop using it to avoid constantly interrupting my classes. One press of the button would either skip through 2-3 slides at a time, or the delay would be so great that I'd push the button again and after several seconds it'd follow orders. Other days it just wouldn't work at all. I was literally standing 15 feet away from my laptop whenever this happened. After a frustrating semester with this presenter I finally broke down and bought a Kensington, which is what my professors in graduate school always used.
Is the review positive or negative?
