Which to choose?

Hi all,

Trying to decide on a new toilet and being a long term prospect we are going for a smart toilet. I do like the integrated units and the ones with the auto open close etc though not sure of the reliability of some of the units.

At the moment I am thinking of the Johnson Suisse avanzo but with a standard height - it may be too low. The only other options I see in a similar price point and features is the Fluva range out of China but I cannot find any detail on them (like manuals and reviews).

Appreciate it if anyone has used these and liked / disliked - or if you have other suggestions?
