Glad I Purchased Two Bottles
I can't wait to share this product with my daughter (who has long hair).  My shower drain was starting to slow down and I dreaded getting out the caustic Draino to take care of it.  I had seen Professor Amos' drain cleaner being promoted on late night t.v. and decided to order some from Amazon the next morning.  When the package came, I went upstairs and poured the recommended 10 ounces down the drain and promptly forgot to go back up and rinse it down.  The next morning I took a shower and remembered the product because my drain was running free and clear.  I'm convinced--I'm going around to all of my drains now and giving them a dose of Professor Amos as a preemptive strike against clogs.
