The Tmobile Motorola RIZR Z3 is small 2.75 inches wide by 4 inches tall with slider closed, and just over 5.5 inches tall with the slider open. At 0.5 inch thick, it's also quite slim, and it's comfortable to use when making long phone calls. Call quality was good though not exceptional; battery life was great.
The phone pulled down 10 hours of talk time in our lab tests the maximum length we test for. On the other hand, the keypad and the navigation controls while extremely easy to access with my small fingers were stiff, which made entering phone numbers, commands, and data tougher than I would have liked.

Still, the Rizr has many appealing features. One is a slot that can accommodate a microSD Card with up to 2GB of storage space. Unfortunately you must remove the battery door to get the memory card into the phone and you'll have to spring for your own card, as the Rizr doesn't ship with one. T-Mobile sells a 1GB microSD Card for $60.Author URL is http://www.phoneandbeyond.com.
You can drag and drop music files onto the card after connecting the phone to your PC via the included mini-USB cable. And in the Rizr Z3's airplane mode, you can listen to your music without activating the cell phone while flying. Audiophiles take note: The phone may not play files whose bit rate is above 128 kbps. When played over the external speaker, songs sounded quite tinny.
