It was a little wider at the mouth than I anticipated, and I thought the light was only blue - but it's blue (cold) red (hot) and green in the middle for warm water.  It's a big hit with the kids and guests that come over.  Going to put an ambient light in the bathroom so that it's always dim and the faucet really stands out.  I only docked one star because sometimes when you go from cold to hot it gets confused and starts flashing or doesn't switch over but overall, fun faucet for the price
