The change from side my side older machines is a big adjustment.  The old dryer had a door that would fold down allowing clothes to rest there as you gathered them from the dryer.  With these machines, you have to be careful that things do not fall on the floor.  Other than that adjustment, they work very well, take up much less space.  I really like to operational pieces in the middle instead of at the top of the machines like other stackables.  This single unit is the best way to do.
