I purchased this phone for my 13 year old. I wanted her to have a phone to get a hold of me and for me to stay in touch with her. I did not want a smart phone or anything she would have internet access with . So many teenagers are addicted to there phones constantly sending texts and on Facebook. She has computer time after school to do those activities. I am going to dodge that bullet as long as i can. This little phone is durable, has good reception and a nice size for pocket or purse. Reasonabily priced it is a good phone with no frills. Performance Does everything I want it to do. Voice Quality I have had no problems with the voice quality. She always comes in loud and clear. Battery Life I am not sure about the battery life. I assume it last for days since she is not on it very much.. yet.. Durability One thing i like about flip phones is that they are usually very durable. I had one for years. They with stand being dropped over and over. Ease of Use NO frills so very easy to use. Nothing to problem or anything. Design I love the flip phone design. Makes it smaller and more durable.
