I was always very pleased with the previous model of Conair's Infiniti Pro 1875 Watt Salon Style hair dryer. For years and years.  I purchased a new "upgraded" model of my previous model only to discover that the dryer is smaller and the amount of air it blows is much less than previous one.  (I tested it .. it is very noticeable.) It took much longer to dry my hair without the shine that I am used to with old model.  
Not a good upgrade in any way, shape or form..IMO.
