but I am glad my wife bought me this one
I was given this as a gift and have used it twice now.  All I can say is I was missing out trying to trim my beard by hand before.  This helped make my lines crisp, straight, and even.  I looked at getting a metal guide, but I am glad my wife bought me this one.  It is easy to use and makes trimming my beard very easy.
