FOR THOSE WHO HAVE BACK ITCHES AND NO ONE TO SCRATCH THEM THESE ARE GREAT! I CAN'T THINK OF HOW MANY TIMES I HAVE A BACK ITCH AND I RUN AROUND THE HOUSE TRYING TO FIND SOMETHING I CAN USE TO SCRATCH IT. WITH THESE IT IS EASY AS HECK TO DO AND IT FEELS WONDERFUL. THE CLAW IS JUST RIGHT AND IT EXTENDS TO GET ANY WHERE ON THE BACK. IT IS ALSO GREAT FOR THOSE WHO WITH SHORT FINGER NAILS ANYWHERE. I DO HIGHLY RECOMMEND THESE SCRATCHERS WITH OUT HESITATION! WELL DONE TO THE SELLER!
