I just got my very first smart bidet toilet and very happy with my chose. 
I check the other brands and models but all are unnecessary expensive. 
This one definitely good for price and performance. 
The installation was little bit tricky at first look but then l figured out and turns out very simple.
I did not have an outlet next to the toilet area but l used extension cord for temporary, l will get an outlet there when l remodeling the bathroom, so far it work pretty well.
One down side l can say is, it needs battery for bidet screen eventough it has a wire connection. 
Good thing is it comes with installed battary and one extra battery for future. I dont know how long it will last that battery but we'll see.
Other than that very happy with functions.
