Had all the features we wanted in a bidet.  Installed by plumber. Didn't take him long so it must have had clear instructions.  Love having the remote vs. controls on a toilet seat.  Haven't used all the features yet.  My husband thought the instruction manual was a bit difficult to understand.  I didn't bother reading it as I thought the pictures on the remote were self explanatory.  Looking forward to a heated seat this winter!!
