Precipitation chart way off
This is fine product–Rainbird sprinkler heads are well-made and function well. However, the chart next to the photo on the Amazon site is deceiving. It lists the precipitation rate in inches per hour that this head can deliver. Unfortunately these numbers are way off–by a factor of six! This is the result of a small part of a chart from the manufacturer’s website being recreated here without the footnotes: this rate assumes overlap from other sprinkler heads nearby–a 20′ spacing if your spray radius is 40′. So instead of putting down a half inch of water per hour, you’re only putting down one sixth of that! The snippet of a chart here defies physics.
I give the product 3* because it can’t meet the numbers as advertised by Amazon.

Quality product and fast shipping
Replacement head for Rainbird sprinkler tower, this was better than expected. It replaces the original plastic and metal head and is 200 x better than the original head. Seller shipped quickly. I am very pleased.
