Call quality is excellent. Bluetooth capability is awesome! I love that these phones use normal size rechargeable batteries (previous phones I've owned used proprietary batteries that were expensive to replace). Overall I am very happy with this item.
I am replacing my old Panasonic cordless phones I had for at least 7 years. I used all three handsets every day and they finally wore out. I am upgrading to the bluetooth style. I synced it with my cell phone and it works great. I love having the option of using it with a cell and home phone.
