I am sorry about having to give 3 stars. This is partly my own personal feeling. The product is for the most part good- as good as you may expect. Why then not 4 or 5 stars? Because (for my toilet at least) it is difficult- to adjust the device to the backpart of the toilet seat. As a consequence the hole on which you have to do your duty- is rather small. It is like pooping on extreme difficulty :). The device itself does it job- your behind feels nice and comfortable- while performing these high concentrative tasks.
