Installation was quick and easy.  Works like a charm.  I can multitask at the sink and easily turn on the faucet with my hands full.  I like the automatic shut off.  I appreciate the long hoses to attach to the water values because it eliminated one set of connecting hoses.   Friends are already asking me where I bought it. 
    It would be great if there was a wall plug-in adapter kit since crawling under the sink to change batteries will be a real pain.
