After using the Bio Bidet BB1000 for almost a year, I can assuredly report that it performs all functions as advertised for both myself and my wife. She was a bit confused as to why we would want to buy an expensive toilet seat at first, but it was soon "love at first sit". The 'aim' is perfect for both of us, even though I am much taller than she. The remote control has handy settings to adjust how far the sprayer extends as well as temperature controls from cool to very warm. As a sufferer of several GI maladies, I find its 'whirly' mass of water very effective and comfortable at loosening stubborn constipation. I think that the BB 1000 offers the best combination of features and solid engineering compared with its competitors. It costs about $500 if you shop for it online.
