They look cheap, but work well.
I gave this a five star rating based on fit and warmth.  I am using these for those mornings when my steering wheel feels like a block of ice.  They warm up in a matter of a minute or two and so far they are working well.  The only downside is that look shiny and cheap, but I'm sitting in my truck and not on a fashion runway so that doesn't matter to me.  Warm, comfortable, and they do what I need them to do.
Rating: 5 stars
