I bought one the last time it was on Woot.
All I can say is WOW! It is the most impressively bad product I have purchased in recent memory.
At first… how cool, the color changes from blue to red when the water gets warm. How slick! Nice bit of ambiance.
But then…
About 2 weeks later…
eeeeeeeeeeeee rrrrrrrrr eeeeeeeeeeeee eeeeeeeeeeeee eeeeeeeeeeeee rrrrrrrrr
The thing starts screaming like the bearing in the motor was already giving up the ghost. WTF? And what happened to the light?
No… wait… It’s working again…
eeeeeeeeeeeee rrrrrrrrr eeeeeeeeeeeee eeeeeeeeeeeee eeeeeeeeeeeee rrrrrrrrr
No… Wait… It’s not working…
Eventually, the screaming died down to a mere occasional bout, and the LEDs somehow manage to put out a faint blue glow, no matter the temperature.
Bottom line, if you want a cool LED shower head, this one is awesome if you only plan to use it for a couple of weeks total.
