My doctor recommended that I purchase a bidet unit. Because I did not know anything about a bidet and how it would be beneficial to me, I delayed several months in making the purchase. I had it installed one week ago. It is wonderful. So sorry I delayed so long ot purchase it. It is easy to operate, provides a soothing wash to the posterior area. It has already improved the severe skin irritation i was experiencing and has drastically reduced the amount of toilet paper I was using. I would recommend it to everyone.
