5 out of 5 eggsMust have

Pros: It works.
If you have a Cisco 794X phone with a Plantronics headset and the lifter isn't doing it for you, replace that lifter with this.
Users aren't tied to their desk to press the headset button.

Cons: I realize this is specific to Cisco Phones, but it feels like it should have been in the Plantronics box instead of the lifter.

Other Thoughts: Now I need to add $50 to the price tag on a new CS70 headset. These make the headset usable. Without it, they are a mess. With it, they do what you expect.
