I'm glad I finally got one, it's an amazing improvement.

I waited for a long time because I thought I needed an outlet to plug it in (for warm water), but it turns out that cold water is totally fine. So you just attach it to the existing valve right next to the toilet. It's fairly easy and not expensive (< $100)
