Product review (5 stars): Quality Silicone
I'll give you 5 stars even though I was hoping the silicone would not be silicone.  I've had these before and everything sticks to it.  But your service is great and it was my fault in ordering silicone.  It's all I can find.  I like the plastic with the magnets.  I found one mail order catalog that has them on sale (probably getting rid of them).  But I'm using the silicone and the quality is great. They are good quality - it's me that likes the older stuff.
