The water pressure is too punishing for external hemorrhoids. The spray is very thin compared to a full bidet. This is completely useless and more messy and smelly.

This tee has a handy on/off valve that can be used to isolate the bidet from the toilet flush valve. It's the only 3 way product with different diameter that we can find. This one is tight and leak-free.

A bit tricky to install, better to add some installation guide videos or paper steps. Works great. Was easy to install and works well.
