Last week was my first install of my first unit. Overall I am very happy and have gotten compliments. My Mother in law did not notice for two days. The only issue is how noticeable the poly band is to the touch. Between it and the glue, it feels like a small speed bump. How much less life will I get out of a unit if I order with out? I guess the cleaning is not as easy? Is the outcome much better? I would like my wife to b able to run her hand without having a big bump.
