I totally prefer this CleanSpa over those units that mount under a toilet seat. They have, at least for me, unnecessary extra features and require a more involved cleaning method. I mounted  the bracket that holds the spray handle on the sink cabinet next to the commode for easy access and aesthetics. I also have other Brondell products that I all gave 5 star ratings. 
I've used bidets, or 'bidet like' features my entire life. I even have a portable Brondell travel kit. I only have toilet paper at my house for my quests whom aren't familiar with these devices. Several of my friends now own these products after trying them out at my house.
