Product review (5 stars): Good product
I've been using this for about a month or so, and haven't burned myself yet on the oven.  I used to, occasionally.  I haven't really "tested" it, but I rely on America's Test Kitchen/Cooks Illustrated (same company) that it does work - they actually did test it. They're simple to snap on, and then you don't have to think about them again...they just sit in your oven, keeping you safer.  I highly recommend this for anyone who cooks/bakes a lot...and is occasionally accident prone :)
