this is the first gas dryer i've ever owned.  i find that i mainly use the manual timer the most as it allows me to determine how long i want the dryer to run.  i'm not a fan of the eco dry as it seems my clothes do not get dry enough when this feature is on but no worries as it is easy to turn this feature off.  i absolutely love the wrinkle prevent feature which keeps the dryer running with no heat so that clothes are not overly dry.  so far, my clothes come out wrinkle free.  the lint filter is nice and large and easy to access and clean.  i'm looking forward to the lint filter indicator to prevent blocking the dryer's air intake.  i've been down that road before with another dryer and it was costly to repair!
