CI have changed my life for the better! I never heard sounds of a bird or bacon frying until I turned my ci on... and I'm not saying that if u r deaf and don't get an ci that u are missing out because that is a personal choice, but I didn't realize just exactly what i was missing out on. I love to hear my children talking, birds, crickets, pond frogs, wind moving the leaves on trees, and etc. I go could go on and on but I will say this if it wasn't for the ci I wouldn't be able to hear all the wonderful sounds and voices i do hear. The benefits outweighs the negative by far. I simply can not function without mine anymore it has become my way of life!! So I say Thank God they came out with this wonderful technolology for me and my family!
