I have used this for years now and would recommend it to anyone, were it not an awkward subject to bring up. It not only leads to a greater cleaning and much less use of toilet paper, but once you get the knack, it relieves constipation and straining.  Unlike my other bidet seat, the Smartbidet extends a little further, giving a more vertical spray where it is needed.  For the same price as my other one, it adds a heated seat and a warm air dryer. You will be glad you got one.
