I installed one at home. Cost is an issue especially when you need a gfci outlet installed behind the toilet. But if you're willing to do all that then:

• Water is heated by the unit
• The spray is direct to center. Doesn't deviate unless you don't sit correctly.
• You only have to wipe once if you want to be sure, but the bidet comes with an air dryer.
• Some benefits is if you have hemorrhoids it doesnt irritate them like toilet paper and it does feel way cleaner than tp.
