Bought this as a more modern replacement for an old Moen fixture I had. I have lots of experience with Kohler and really like them. Products are well built and customer service is easy.I really like tech so I opted for the waive motion model to start and stop water from the faucet. I will say it takes awhile to get used to the motion as opposed to turning the handle on and off. But once you do, you really like it. And a lot less touching of the fixture with dirty or greasy hands and fingers! It stays cleaner...a big plus!Installation is straight forward, with directions easy to follow. Replacing kitchen sink fixtures is always a pain because you need to get underneath the sink and move your arms and body in difficult and constrained spaces. But this unit has some thought into the installation. The brass nut with the two screws that you tighten down on the main neck of the fixture once you can know longer tighten the nut by hand makes sure the fixture stays solid in place. The water lines attach easily, assuming you already have 3/8" male faucet shut off connectors already installed. If you don't, this will require lots of pre-plumbing work to install those, and it won't matter which fixture you buy - this will become a much bigger job prepping for the install.The installation of the motion activation hardware underneath is "plug and play" and in spite of being an easy click of the faucet lines into the motion activation controller underneath, there are no leaks!!!What comes with the unit to power the motion activation switch is a battery pack and 6 new AA batteries. But I opted to buy an optional plug in power supply. Many of the motion activation units on the market are battery only but Kohler offers an option for a plug in power supply. If you have a spare electric receptacle underneath to plug into, this saves the hassle and expense of replacing the batteries. Kohler offers a power supply to purchase and there are several other power supplies offered for this model on Amazon, but this is the one I chose and it's working great - just search Amazon for:T POWER 9V Ac Dc Adapter Charger for Kohler Malleco Touchless Faucet R77748 K-R77748-SD K-R77748, K-R31498-NA K-R31498Included soap dispenser is easy to install - pretty straight forward like most of them. I opted to buy an optional soap dispensing tubing kit that allows you to draw from a large container of dishwashing soap you park under the sink so refills are easy and infrequent. Pretty easy install but I had to attach the flexible hose to the short plastic tube that comes with the dispenser as opposed to directly inserting the flexible tube into the dispenser unit. No biggee and it works great. The soap dispensing tubing kit I bought on Amazon can be found by searching this:Soap Dispenser Extension Tube Kit with Check Valve, 47" Under Counter Soap Dispenser Tube for Kitchen Sink, Fit Most Soap Containers, Powerful Suction, Never Fill The Little Bottle Again SonTiyThe finish on the unit I got is a nice brushed nickel. Styling is simple and classic but with a contemporary flair.I've had it installed for only 3 days but it's working flawlessly. At this point, I highly recommend it! If I have future issues, I intend to write a supplement..
