Product review (5 stars): Awesome!
I stuck it on this morning, and so far so good. I will make an update should any issue arise. i was nervous to buy because some people said they took it apart and whittled it down to be able to use the slider. but there is no problem with mine. Do make sure you press the slider firmly with your thumb and then push it across. it makes it easier to push. very clear to read, even my mom can read it without her glasses.
