I read the Mr Money Mustache Blog fairly regularly, and recently he had a post about showerheads. My showerhead is from around 2000 and is one of the 2.5 GPM models, which I always thought was "low flow" Apparently there are newer low flow...1.5 GPMs and there is little noticeable difference.

He breaks down the cost effectiveness of switching in the blog so I won't go into it. But, basically for two folks taking fairly short showers several times a week the change to the super low flow showerhead saves $37.18 per year.
This sounds like a no brainer to me since a highly rated shower head is only $10 on Amazon.com Save money and use less resources in water and electricity. I'm ready to pull the trigger but wanted to know what do you guys think???
