Summary: I'm happy with my LG CU405 phones. I have a smart phone too but when I just need a phone, I like the LG CU405. They're inexpensive, I can carry an extra battery or two, they're durable, and are bluetooth compatible. When I have a problem, I just take out the sim card and put it in another phone and I'm ready to go. I've probably only spent about $50.00 for phones for my wife and me in the past 5 years.
Summary: It is ok for a backup phone when I don't have any other one to use. It works fine for the type of phone that it is. There is no camera so it is for the phone feature only. But that is ok if that is all you want.
