My 6 year old daughter had not had a dry night in over two years. After one week of using the alarm, she had her first dry night. During the second week of using the alarm, she was dry every other night. Since then, she has not had a single accident and has been dry for over two months straight!The ultimate with options was nice because we could select the sound that she liked (there is one that sounds like a telephone that she liked best--some of the others were a little scary to her). My daughter did not like the vibrations, so we just turned that option off after the first night. I had put off purchasing an alarm thinking that she would eventually outgrow the problem, but I don't believe that it would have happened any time soon without the alarm. The process was much quicker than I could have ever imagined and my daughter is so proud of herself now and so much more confident. It was the best $[...] I have spent in a long time!! I highly recommend this product.
