When we upgraded all the toilets in our home to TOTOs, it was the perfect opportunity to get electrical extended & install this washlet in our primary bathroom. I originally ordered the S7 without night light & auto open/close lid, but realized I wanted those features, and John of Premier Bidets was able to change the order before it shipped. Ordering through Premier Bidets was extremely easy and straight-forward, and John is highly communicative.
I've wanted a washlet for over a decade and have always had cold water bidets (hand-held, NEO, Tushy, etc.) as well as toilet night lights.
I am so glad and have zero regrets with TOTO's S7A washlet, which is a huge upgrade. It is far superior to non-tech bidets; the warm water, heated seat, and fan are all great features. The price might seem steep initially, but completely worth it for the comfort and convenience. If you need to justify it, calculate the cost per use over 1, 5, and 10 years (highly recommend this exercise).
I did realize after installation that I expected the toilet to auto-flush, so I'll be ordering the additional product to integrate that into the washlet.
