I use it with a Toshiba phone and setup was easy. I love it because I can answer the phone while I am away from my desk and still be hands free to work on a computer or take notes. I have a few customers complain that they can't here me but most have no problem. Sometimes just hangs up for no reason or won't pick up the first time or has a delay so I hit the button again and then it picks up and immediately hangs up.
Wore out the gears and have to replace the unit after 2 years.
Great product, this is my 2nd handset lifter (after 5 yrs) this combo unit (receiver and lifter) is a must for those on the phone a lot and who need to type etc while talking, best part, you can walk around the office and the caller won't ever know it. A+
If you are glued to your desk, then don't bother with the lifter. However, I need to be in storage, out on the deck, at a Associates desk or wherever, and being able to answer the phone from all around the office makes the phone lifter an essential to go with my headset.
