I bought this over a month ago and have been very satisfied with the performance of the dryer so far.  I don't have the long dry times maybe as some other reviewers have stated because the matching front load washer reduces the amount of moisture in clothes before it gets to the dryer as it is.  So i suspect that is why dry times become more elevated with top loaders, as it was probably designed for the front loader.  The app is great becuase it lets me know how many loads i have done in a month and when i have to run the clean cycle, clean lint filter, etc.  Even though this was a little more expensive than standard exhaust to outside dryers, I just got my electric bill and already starting to reap the rewards.  Waiting to get my fuel bill to see a drop there since this dryer no longer exhausts all the heated air in the house back outside!
