Product review (5 stars): No oven should go without one!
I own a set of the Oven Rack Guards and this is one of the best kitchen inventions I have ever seen.  I am a kitchen gizmo guy and I love the latest and greatest.  The Guards are great, machine washable (I just leave mine in all the time) and idiot proof!  What the guards lack in style, they more than make up for in function.  For Christmas this past year, I purchased seven additional sets for gifts and those people are now in love too!
