i have a backpacking bidet (culo clean specifically) and I would say it gives mixed results. basically, you need to practice and develop a technique to “get the most” out of it in terms of water usage, how clean you can get, etc. I don’t have a normal bidet so i have nothing to compare it with and maybe my technique isnt so good. mine gets me mostly clean but i still need a square of toilet paper to make sure in almost every case. better than not having it, but not the results I was hoping for.
