I really love the slider, the fact that you can't see all options at once makes your reflection less automatic, you consider each one as you slide up and down.
I'm going to second this. I loved the slider and shades rather than a specific number. It gave me a way to guage where I felt like I was. I also liked that there was a description to say, hey this is what a 10 really is, don't just give a 10 because you want your job to be exceptional. In my case it helped me be more honest with myself (I'm a habitual 10 or 1 guy.
