does an ok job
i used this product for major squeaky floors. it worked well in one spot, but another area that is really bad it did nothing for.  It helped on some steps.  I suggest this product if your floors squeak a little.  My floors were so far gone, that I just had the carpet pulled back and redone.  I had hoped this would work magic.  Alas it did not.  Definitely do a couple test spots so you know how to properly work the system.  A couple I didnt screw down far enough so i had to get a hammer to get it all the way down..
