I really dig those expensive LED faucets that glow blue and red to warn you of the temp. Here's my review of the $20 nozzle attachment version. As you'd guess, I'm giving up a thing or two by skimping:
Yeah, we've shown you a couple LED faucets before, but this one is different. Check it: rather than just making your water blue, which makes you feel like you're doing the dishes with antifreeze, it changes color based on the temperature, making you feel like you're doing the dishes with either antifreeze or Gatorade.
