Installation was pretty straightforward, the mounting mechanism is slightly different than a normal toilet but may be normal for this type of toilet. Either way, it was pretty simple. The power cord for it is pretty long which works for me as I have it running off an extension cord while I am waiting on an electrician to come to install an outlet, but there is a huge cavity in the base that will make it easy to hide the excess. Operation is what you would expect from this type of toilet, coming from Japan all the functionalities are there that I am used to. I just wish the length of the seat and the actual bowl were a little longer.
