Rated 5 out of 5 by from Nice addition to the headsetPeople were always starting up a conversation while I was on the phone with a customer. This gives them a nice visual that I am engaged in a conversation. works as advertised.

Rated 5 out of 5 by from Online IndicatorThis product performs as designed and easy to set up. The only think that would work better is an add on proximity alarm. This feature would automatically reach out and smack the individual who chooses to ignore the indicator. Yes, sadly there have been a few.

Rated 5 out of 5 by from works great - Would like 360 viewThis product works and very easy to install. I wish there was something that gave a 360 view. It is designed to work unfolded from the base. Some of my employees have stated that a single bulb light that could be seen 360 would be better. We have to arrange them in a way that faces in a direction so it could be seen by the majority of co-workers. However, it is better than not having one.

Rated 5 out of 5 by from Works Great!!It was easy to install & works great. I did put a little sign under it saying "Hi There! If this light is blinking, i am on the phone."

Rated 5 out of 5 by from Works as designed.This works just fine. If the product were domed with 360 degree visibility I would be more enthusiastic.

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!!
