I wanted a basic flip phone, and the M370 is just that. The volume is nice and sounds clear, although it sometimes sounds "choppy" and seems to cut off the first fraction of a second when the other party speaks. Texting is sometimes funny also, where rather than toggling through the characters, it will insert mutltiple characters. For example, pressing the 5 key three times to select the "L" will sometimes insert three "J" characters istead. Battery life seems okay.
Easy to see, big buttons
Choppy voice, funky texting
