KOHLER R77748-SD-VS Malleco Touchless Pull Down Kitchen Sink Faucet with Soap/Lotion Dispenser, Vibrant Stainless

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-R31498 Included 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 SonTiy The 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..

I ordered two of these for a home renovation. One box was missing the soap pump. Amazon would only give me $60 rather than replace it. And Kohler wouldn't do anything. The touchless feature has never worked. Three months in one of the faucets started to leak - all over my kitchen floor. Thankfully Kohler did replace free of charge. But now the second one has also leaked. Clearly this is a very defective unit.

Easy installation, works as it should, absolutely no issues. Looks really sharp too! Filled the soap dispenser with dish soap, which is really convenient when doing dishes. Would definately recommend.

Perfect replacement faucet for us! High marks for the styling, touchless design, completeness of the kit, clarity of instructions, ease of installation, matching soap dispenser, and Kohler reputation. I had no installation or leak issues and the faucet works flawlessly. I have seen some reviews critical of the sensor placement; this is subjective. We are satisfied with the sensor placement and now its operation is intuitive for us.

Easy to install. Looks and works great. Buy the optional power adapter instead of using battery pack we had issues with sensor reading. Only issue i see is now wanting to upgrade my sink with thicker steel and deeper sink bowls as water likes to splash onto counters using shower head function.
