With all the talk of toilet paper shortage, I thought I post this. Just bought this the other day to replace the Smartmi, the damn thing stop working just over 18 months and wow truely can never go back to the cold dead normal toilet seat. I am supprise Bunnings start to sell these. Got all the features of the whale sprout which include warm air blow dry (my favourite feature now). Instead of the app control it have a wireless remote magnetically attached to wall which is a lot better then the app control in my opinion. For extra $60 more then the whale sprout you get Australia approve water marks and power cable, and 3 years warranty..yes a backflow valve and T adapter included.
