This showerhead is really cool. Looks to be well made, does not leak where it screws on. I don't know how this thing works but it works exactly as described. With the water running it looks like the shower head has multi colored lights inside but there is no electricity involved. My son thinks it is awsome. He now likes to shower with the window shades down & the lights off to see the shower head & colored water!
Nice for the price. Lights up and colors transition smoothly. Not as bright as i would like and every other similar product adjusts color according to temperature, just not this one. To be honest though, even though I have a 16 function high end wand I just bought and took off to try this out, I think I'll leave this one on....
