Product review (4 stars): I Wish They Made These In Black
I bought these a few months ago and they work great at preventing burns.  The only problem I have is that are beige and stain easily and always look dirty.  I just found and purchased the silicone brand and I'm in love with them because they stay clean and are maintenance free.  The silicone oven guards are much prettier and professional looking but they only work up to 450 degree temperatures (so they are not quite as heat resistant).  I would recommend the silicone for the oven and these for a smaller toaster oven with the rack closer to the heating element.
If this brand came in a black color, they would be perfect!!
