Question: I like the color and the sizes of these lids, and plan to use the large ones to cover my pot on the stove top. Unfortunately these are not 100% silicone and contains fillers as you can see in the pinch test. Google search shows silicone products containing fillers are not recommended for use under heat.

Answer: Failed pinch test, not 100% silicone contains fillers

Question: This smelled like toxic chemicals

Answer: Awful material. Chemical smell from the imitation leather

Question: To be honest, my before and after has not changed a single decibel. I've used a wi-fi sniffer. I don't know if it's my router (Verizon FIOS) or my walls. So I want to be careful telling people this device doesn't work, but it does nothing for me. If I determine what the issue is, I will gladly update this review, but after two weeks I just have an empty wallet and a larger antenna - but no better signal.

Answer:
No difference vs. stock antenna. Could be my router. Will do more testing.
