YES!  Much better than the standard product.
YES!  I wore out a previous Sonicare brush handle.  Got a new one.  The brush seemed stiff.  I have always been told by my dentist and his hygienists to use soft bristle brushes, both for manual and power brushing.  I ordered several replacements from Amazon and took them to my dental hygienist.  She and I agreed these are softer, and the best of the bunch.
