Summary: I am currently purchasing my second LG Glance, with the first one I owned serving me well for a little over 4 years. That is with a fair amount of (unintentional) abuse--dropping it on the street/sidewalk. The call quality is very strong and clear, much better than I expected. The camera's not great, and only captures still images and not video, but that's not what this phone is about.
Summary: I'm happy with how slim it is and the fact that it works with Verizon's most basic plan. The only thing I'm not used to is the central knob, which is a little hard to operate because it's small and operates as a "swivel" (instead of the basic up-down-left-right clicks, it can move in all directions). Other than that, great quality calls and easy use.
Summary: Slender and surprisingly fast. Sturdy but lightweight. Mine's scratched up pretty bad -- I have this habit of dropping it on the sidewalk when I'm walking somewhere -- partly due to the phone's small size but mostly my clumsiness. There's no video recording or flash which is a bummer (but the camera's so pathetically low quality that it doesn't really matter).
Summary: This is NOT a smartphone, so only has the basic functions, but they work well. The battery lasts a long time (especially an extended battery). It powers on or off in a few seconds, is simple to use, and works well as a phone. It even does bluetooth. (I have a Mifi and Samaung Galaxy player 2 and a few other things for Apps when I need them). Small, but with a good sound.
