I only used the retrofit toilet seat/bidet combination (not the full toilet, so if it is, i’m not able to give you the best info)...However, if you are looking for a toilet seat/bidet combo, I’d recommend the washlet S500e or S550e. I prefer the S500e version as it does not have automatic lid, which has been a nuisance (can turn off though). They are quite low profile, easy to install (per my super), and really helps save a lot of toilet paper. After using the older brand S350 for a few years, i recently changed to the S500e. Similar in function but nicer remote. The oscillating/pulse features are great and makes you feel very refreshed (hope this is not oversharing). The bidet is one thing i miss after traveling.
