Because I am looking into putting up crown molding (still need to work
on my popcorn ceiling problem) I looked into the easiest way to do
it. I stumbled across the EasyCoper on 'the' google and I looked into
acquiring one (I got to meet the inventor too.). I wrote a review on
my website for those that are interested. I have never put up crown
before, but I honestly can't see coping crown any other way. It takes
a little practice to get the hang of it (I cut into mine a few times
with the jig saw).
