Let me just start by saying there are TWO versions of this faucet. Why Moen didn't differentiate between these two by a model number, who knows. It makes it very confusing when researching. I have the new version and my review will mostly focus on that. My review will focus on what is wrong with this faucet. We can all read what Moen says is right, no need to add any more to that. First, the ORIGINAL version of this faucet came with 7 hoses and allowed the faucet to work as a normal faucet when power was disconnected. It has a GRAY control box. The 'new' version, I hesitate to call it improved, has 3 hoses and a BLACK control box. The new version will not operate without power no matter what. Other differences include materials for the faucet itself, length of the extending hose, even water volume. I gleaned this info from reading dozens of reviews and comparing the dates written. Moen's website even has a blurb about the limitations depending on whether you have a gray or black control box. Second, I find it incredible that a top-of-the-line featured faucet is standard with batteries and optioned with power. I can't imagine the battery box with the 6 Duracell batteries included would be cheaper than the AC power wart. I think Moen uses this as a way to price gouge customers as they price the AC power source at over $35. The same product unbranded is about $6 on Amazon. Third, there's an even newer version of the AC power source option. This one includes an interface that incorporates both AC and battery sources, utilizing AC when available and switching to battery when AC fails. Now THAT should be standard on all new faucets and a free 'fix' for all existing registered owners. You have our addresses, Moen. Do the right thing and quit charging your customers for fixes to poor design. Even worse is the amount they charge for this little bit of electronics; over $135 !!!! Shameful! Fourth, the front sensor is too sensitive. It should not come on until something triggers it between the water flow and the sensor. Instead, it is triggered well before a hand, cup or other object comes under where the water will flow. However, the goose neck does swivel, (more on that later) and the sensor set to point in a direction that's less likely to be false tripped while using the sink for other applications. I sorta found a way to make the front sensor less sensitive. Start by powering down the faucet. Next place a piece of scotch tape over the sensor, pressing enough to remove air bubbles. Power back on the faucet and let it go through it's initialization process. (About 20 seconds or so) Remove the tape and test for effect. I found the front sensor is much less sensitive this way. Actually just a hair too low now, so as I need to get about half way between the water flow and the sensor to keep water flowing. However, I've not been able to find any other way to adjust the sensitivity other than this one. Fourth, water volume is rather pathetic. Somehow there should be an adjustment to set the flow volume to something a little more robust. This is especially noticeable when using the spray feature, where I try to blast off some food from pots and pans. Fifth, the hose is too short. Fully extended, it barely reaches the far corners of the sink. Videos Moen hosts show the thing filling pots on the counter surface next to the sink. Maybe the original version had a hose long enough, but not the new version. Sixth, no soap dispenser accompanies this faucet. Just about all other brands include a soap dispenser, either in the box or as an option. Not so here. Moen does sell a soap dispenser at at least twice what the market averages for one, but the color; oil-rubbed-bronze, is quite different than that of the faucet. For this price point, the soap dispenser should be included just like the AC power source. Seventh, the retract is sorta wimpy right when you need it most; when the head meets the neck. A magnet design would really improve this problem but at least a little heavier weight to get the concept to actually function consistently would have been nice. There are several good features and I'm sure I'll appreciate more as I become more familiar at using it daily, but so far, Moen's done a fine job describing what I've observed just fine. Oh, one pleasant surprise was how easy this thing is to install. One nut mounting, hook up hot and cold water lines, snap fit the spray hose and plug in the battery pack. ****EDIT**** I tried submitting this review in it's entirety on the Moen website but it was rejected. I replied back as to why and they sent me a free AC power adapter; part #169031. This is the fancy one that will tie in the original battery pack and switch to battery if there is an AC power failure. Moen lists the cost at $135 on their site and I think it's something like $100 or more here on Amazon. I guess it pays to bitch once in a while! Ha! Anyways, I raised my review from 3 stars to 4 stars just for that.
