Summary: The unit can make and receive calls even when power is out. The phone doesn't include an answering machine, which reviewers say is important but doesn't prevent them from purchasing the Clarity XLC3.4, as there are few similar options available on the market. Expansion headsets are available separately, but are pricey (Est. $65 each).
Pros: Talking caller ID and dialing, Amplified sound and ringer, Large buttons and letters with high-contrast screen, Can make calls when power is out
Cons: More expensive than most cordless phones, No answering machine
