The product was easy to install with the parts included. I used a Tongue & Groove Plier to remove the aerator from my faucet and to install it. Works perfectly and as described. This unit is able to attach to the sink faucet making it easy to get warm water to the unit. Love this idea specially for winter months. A great benefit of connecting to the sink faucet is the option of getting warm water. I will buy a second one for the other bathroom. Worth the money.
