The pop up trimmer is much too short.
While this works great as a shaver for a man's beard/mustache area, I have one complaint.  I always use the pop up trimmer to trim along my husband's hairline and the hair in front of his ears (sideburns).  This pop up trimmer doesn't come up nearly high enough to use it for that, and I couldn't see his hairline at all.  My husband only uses an electric shaver once or twice a month for a quick touch up, but I use it every time I cut his hair.  I don't love this trimmer.
