Bought 3 of these toilets on March 24, 2020.  The cleaning feature is great.  However, one of them kept running  3 months after we bought them.  My husband had a heck of a time to  fix it, to stop it from running.  Pain in the buttock if you ask me.  Finally he stopped it. 
Now, toilet number 2 is acting up. Every minute or so, it starts running.  Tried every different way to stop it.  What they call innovative is quite not user friendly.  
Seems from reviews, i might have to replace the flapper seal, which is not cheap, if that is what is needed.    Would never buy this again and NO i do not recommend it.
And i am sure it will also be a good price to have a plumber look at it.  Not impressed.
