Title: Worked Great & Then Stopped
Review: The presentation remote worked well. It provided good control of forward and backword motion for Powerpoint presentations. The RF technology did eliminate the need for line of sight operation. I really enjoyed using the product. Then one day, at the start of a presentation, it quit working. I assumed the battery had died, no one happened to have the special battery on hand, so I put it away.Later, I tracked down another battery for the device, put it in, and nothing happened. I checked voltage levels and the battery was fresh. So, I contacted Keyspan for warranty help. And after 3 weeks have not recieved any response.Hopefully, someday, they'll respond and fix the device. Without the service problems, I'd give the device a 4. With them, it seems your choice is to purchase and hope it doesn't break.
