My friend Larry Adkins reviews shower heads online, and he says it’s not EXACTLY a scam. It just won’t save you any water if you’re not the type that turns on the water and walks away. It must have either a timer or a temperature gauge (not sure which) that just slows the water down to drops after a little bit of time so that you can just go and flip the switch when you’re ready to go and shower. If you’re one that waits for the water to warm up in the shower, you will save no water whatsoever.
