This A/C has been reliable so far and was relatively easy to setup. However if there's one thing I could change it's that there's no way to customize the clean filter warning and the A/C unit completely stops unnecessarily about once a week until I go into the app and tell it that the filter is clean. It completely defeats the point of having that feature there since every time I check the filter is still just as clean as it was a couple months ago when I bought it.
