text: Really cold but excellent.
  
  As far as excellent tracking response I give it 5 stars, only took off 1 star because it's really cold since it's metal, but it's very handy to use when I'm on the couch or in bed watching movies. If I'm needing it for games involving track speed I use it. Might be due to my using the heater sparingly. It also has a good padded backing so no need to worry about scratching any surfaces.
