Rated 5 out of 5 by from Excellent ProductThis Product is easy to use and it significantly reduced the number of calls that were being interrupted. It is so simple; the only improvement that would be amazing would be to have them create a wireless one.

Rated 5 out of 5 by from It works if you tell people about the blinking lightI really like the idea of not being interrupted during a phone conversation just because you are not holding a phone on your hands. My Plantronics ear piece is on my right side so people can never tell if I am on the phone or not. I had to explain to my co-workers what the blinking light meant. Then I added a business card size sign that reads "Hi there! If this light is blinking, I am on the phone"

Rated 5 out of 5 by from Works just as advertisedI had read reviews that this product lit up only when the headset was taken out of its cradle. This unit actually does what it is supposed to do. It lights up when the headset is used - not when lifted out of the charging cradle. Works great and lets people know that I am on the phone.

Rated 5 out of 5 by from THIS COULD HAVE BEEN GREAT!!i bought this to go with my CO54, and when i received it i was very excited!!! then i found out that it only works when you're using the handset lifter. Really? you couldn't have made that clear?? it's such an awesome idea, i hope someone comes up with a way to make it work when you're not using the handset lifter!!

Rated 5 out of 5 by from Ok.The light stays on as long as the headset is on; not when the headset is connected on a phone call. Not useful if you are not using the handset lifter.

Rated 5 out of 5 by from online indicator lightI bought an "extension cord" from Radio Shack so I could place the light where it would be more visible to folks passing by my office, without having to move my telephone. I placed a sign in large letters under the light explaining to folks coming to my office what the light meant. Once they are all trained to pay attention to the light, it serves me very well. 360-degree visibility would be a welcome enhancement.
