Product review (2 stars): These appear to be solid metal
This product is not working well for me. My range is about 1/2 to 3/4 inch above my counter .  The T piece does not stay anhored in the space and they slide all over the place.  I have tried them in every position available, and at best they stay in place if I absolutely do not touch or bump them...if I do, they slide out of postition, thus defeating the purpose.  These are a disappointment.  I was hoping for something either somewhat flexible or that would accomodate for a stove higher than the counter in some way.
