I'll echo the issues with too much water pressure on really cheap bidets. My first one was like a butt hole pressure washer. My second one was more expensive with a tank at the back. Unfortunately, that combined with a rounded toilet didn't leave enough space for sitting. The ones I have now are all Tooshies. I got the ones that can combine hot and cold water, but I only have a hot water hookup for one because I would need to poke holes.
