Query: Great if you dip it in hot water first

This product comes tightly coiled but softens and straightens almost instantly if you dip it in a sink or pan of hot (pre- or post-boiling) water. It's easy to stick multiple cords inside (I have three inside), and comes with double-sided adhesive to seal it to the floor (if you want). I give it four stars instead of five because it would be better if it had the optional peel off adhesive already attached to it -- like the IKEA wall cord covers.
