Product review (5 stars): The ULTIMATE Back Scratcher
I bought this to clean my fridge and radiators... it arrives the same day that a back scratcher did that my wife bought me, which sucked btw.  So after I felt the stiffness of the bristles, I get the idea that it might be a good back scratcher... I'm not sure if there is a better product to scratch your back... the bristles are stiff, but not too stiff, and you would have to use it for a while before it hurts.  It has a long handle so that you can easily reach, plus you can basically hit your hole back in one swipe.  It's fantastic.  As for its original purpose cleaning coils, I think it is really nice and I will be ordering another one for that.
