Had bought as everyone of "junk silicone" that after 5 seconds make you feel the warmth and not a little. Anyway found these wonders and thanks to the support comments, we decided to take 2 (sold individually) .... happiness. At least 40-45 seconds before many feel the heat .... be plenty of time to get out a dish from the oven and unmold the bread in the bowl of our bread machine. Recommended. Serious seller, price, faster than expected period. sum pleased with our purchase.
