Product review (1 stars): newest duets don't need kit
One star may be unfair but the point is this item is not necessary for the newer models of the whirlpool duet dryers, such as the 94 and 95 series reviewed so favorably in Consumer Reports.  Installation instructions available on line describe how to switch the door from right to left.  The procedure takes about a half hour, is a little bit tricky, and requires a phillips and a torx screwdriver.  The average handy person should not have a problem, especially if they don't mind carefully following the instructions.
