Very helpful but poor brush bristles. [SEP] It is such a relief to be able to brush the back of my head!  I have severe RA which has left me with little use of my shoulders, so tools like this are invaluable.  There is one drawback;  the brush itself is such a poor quality bristle that it is hard on my very fine hair.  A better brush on the end would warrant a five star rating.  Really you have to choose between a good brush and accessibility.  Would love to have BOTH!
