Can't live without it!
I have been using the battery powered Emjoi's for many years.  Love them...until now!  The battery operated is more convenient but I will never go back to it.  The power corded model is faster and the results are so much better.  I don't think that the flex roller made much of a difference. This one works in all directions.  Wish the cord was just a little bit longer for convenience.
