Love, love, love them.  I've had another brand for years and couldn't find them anymore, literally using them as they finally fell apart and I had to replace.  Was hesitant about buying these but have come to say that they are my new Fav's!!! Thankful that I purchased and I highly recommend. Have yet to feel any heat coming through and I've baked a lot over these current holidays. If there were more than five stars to give I'd have given more.
