I purchased this item on Amazon in November and used it once, but it didn't quite fit my home's installation, so I'm selling it. The water flow was good, but I felt the temperature dropped slightly when using the microbubble setting. I researched it, and apparently, when water particles become smaller, the surface area increases, leading to more contact with air before the water hits the body, thus lowering the water temperature. I believe it does save water, but it didn't suit me, so I removed it. I recommend it to those who want to stop the water flow with the showerhead button and save on their water bill. ● Condition: I only used it once, but please understand that this is a used item before purchasing. 【Search Keywords】 Water saving, bathroom, bath, saving money, nanobubble, microbubble, massage, scalp, cleaning power
