Rating : - It's just fun
Okay, it does have some functional value so you can see at a glance if it's hot yet like say if you are standing at the stove. Mostly though, it's just incredibly fun. Just a little jolt of pleasure whenever I turn the water on and the blue light comes on. I accidentally left mine behind when I moved and even though I tried to talk myself out of it, I had to run out and get another one. It's also great when a friend turns on the water unwarned and jumps back in alarm :)
