After lots of research online, we purchased a USAbidet for its simplicity and adaptability to our toilet. We have had it for over 14 years and feel it is better than any of the bidets we used in Europe for its ability for directional waterflow. Also, I am a Physical Therapist in a Rehabilitation Unit and recommend the USAbidet for my patients who have had a stroke, a brain injury, a spinal cord injury, and even back surgery. Not to mention anyone with any disease process where mobility is an issue. I have also told my friends how wonderful this product is despite having no medical need for it. Stop now….it is so much easier to use this bidet instead of a wet wipe or get into the shower to clean yourself. The patients and friends that have purchased this bidet are true converts!!! I sing its praises every day!!
