Product review (4 stars): Length advertised is incorrect and do not lay flat
I really want to love these but due to the item being bent in half to fit in their box, there is a bend in the middle that does not want to seal to the counter or stove. One strip was worse than the other, and this defeats the purpose of sealing the gap as liquid can seep through there.  Also, these are advertised to be 22 long which is a main reason I ordered these over other brands, but they only measure 21.  Other than these two issues, I do think they are a great product and could work well.
