Moen Multi-Function Shower Head

What is this?

A shower head with several 'functions.'

Why did I buy it?

The shower head in our home was crap and this was the cheapest replacement I would consider buying at Home Depot when I wanted to replace it. 

It has a few different water settings, which I never really utilize. But all of the settings are a vast improvement over the shower head we used to have. All in all this was an inexpensive upgrade that has a pretty big impact on something I do almost every day.
