Learning curve, then WOW!
It took me a few times to get the hang of my waver.  The way the videos showed was very awkward for me.  But I quit worrying about holding onto the end of the strand and suddenly I loved it!  The waves stay longer than when I use a curling iron and I don't feel like it's doing the damage that curling irons and flat irons do.  I even use it on the lowest setting and it still holds.
