I bought this because I thought the shower very nice effect. Ten leds that light up the flow of water.
The installation is pretty easy, fits any shower outlet. The coolest thing is that you don't need batteries, He lights using a small generator that works with the passage of the water. The shower is all metal and putting a little's enough thread seal tape to prevent leaks.
The leds light up according to the water temperature: Green for ice water, Blue to red and warm water for hot water.
Actually there are five green leds and five red/blue leds. The effect is even nicer when it's dark.
The only defect, as with all these showers, is that the amount of water that comes out is small. In my house, for example, I'm in the penultimate floor, This shower often prevents the passage of water required to activate the heater. Until today I never found a shower led that had high flow. I've tested three!
I made a video about the product. Look at the effect that goes in your bathroom:
Guy, awesome! The only thing I thought is that maybe they did gradually change color. But that would be difficult with a few leds I believe.
