Smart toilets are not cheap.
 

My son just installed two in his home for a cost of $5,000 each. That did not include installation.

Apples and Oranges. The OP posted an add-on device installed on a pre-existing toilet. These are much more reasonable for most people, compared to installing a Toto (or similar) toilet with all the features, which can range from $1500-$6000

Has anyone who has bought one of these add on devices been dissatisfied? It seems that most of the people here that have one like it or love it. I see one post that says "tried it, not for me".

I'm wondering why it's not for you or if other people have installed one and don't like it for whatever reason.

I'm not just talking about the one that the OP sells. There are a lot of these on the market and I'd like to know the positives and negatives. It would also be nice to known which brand or model people liked or didn't like.
