Clarity ClarityLife C900

The Clarity ClarityLife C900 is a slider phone designed for seniors, with large, easy-to-press buttons, emergency features, a built-in flashlight and the option to use AA batteries instead of the included rechargeable battery. Clarity is a division of Plantronics, best known for its Bluetooth headsets. The C900 is an unlocked GSM phone, meaning it will work with T-Mobile or AT&T, and no contract is required. The phone is rather large (4.5 inches by 2.3 inches by 0.8 inches and 5.4 ounces), bigger even than the Samsung Jitterbug (*Est. $150, no contract), but it's meant to be easy for anyone to grip, even those suffering from arthritis. Unlike the Jitterbug, the ClarityLife offers text messaging, although most reviewers are dubious about using this phone for texting.

Matching the handset's large size is its 2.75-inch monochrome screen. While the keypad has large keys, they're flush with the phone surface, making them not-so-easy to press. Other features include a flashlight that can be activated with the press of a button. The phone also has an emergency button -- it doesn't call 911, though; it automatically calls a list of up to five contacts until someone is reached. The ClarityLife has room for 200 contacts (Jitterbug has only 50), and includes call waiting, call forwarding, a calculator and a birthday reminder. Clarity rates the phone's battery life at just 2.5 hours; no professional reviewer has performed independent tests. CNET rates the call quality as good and loud, although reviewer Kent German notes some background noise seeping through.

Reviews of the ClarityLife C900 are rather scarce. CNET offers a full review, and the phone is included in a roundup at U.S. News & World Report; both of these sources compare the ClarityLife with the Jitterbug and now-discontinued Verizon Wireless Coupe (another basic cell phone). Comparisons are feature-based, and no source recommends one phone over the other. PhoneScoop.com provides a number of photos and a walkthrough video of the ClarityLife. Consumer Reports reviews the Jitterbug but not the ClarityLife. We did not find any user reviews, and none of the professional reviews mention customer service quality.
