Product review (3 stars): works
This product works.  I had trouble because my stove was tighter on one side, so it did not fit in as well.  But that was not the products fault.  The only thing I was disappointed in is that I expected them to blend better into the color of my counter top and stove.  They are very noticeable and I wanted something to blend in.  I thought they would have been a more clear to blend.  They serve the purpose.
I had also purchased another set from a different line in black, which I like because blend into my stove and countertop.  I did not return the silicon ones because I plan to use them somewhere else.
