Rated 3.2 out of 5 by 173 reviewers.
Rated 1 out of 5 by One senses ghosts, the other needs to be touched I have three Dryden with Touch20 technology. A short one in a single basin vanity without any problems. And two tall ones on the dual vessel vanity. The vanity is 72" quartz. Black marble vessels. Spacing between the two faucets are 36". I have placed the battery packs as far apart as they can be on the floor of the cabinet. The one on the left closest to the window has spontaneously activated once when I was in another room, and twice when I am either sitting in front of it or fiddling around with the unit on the right. The unit on the right, doesn't do the handsfree feature. It needs to be touched to turn on and off. Lever action on both is fine. The grounding wire has been bolted down but to no avail.

Rated 5 out of 5 by I do love it, it's great, you have dirty hands and want to wash them--just pass them under the tap and wow! No 'dirty hands transfer' to the handles!!!! Your faucet is still clean! Also, people seeing it are really impressed. I think it will be a great water saver during this drought period, because it has an automatic shut-off. Hey, it even looks great! July 25, 2014
Rated 3 out of 5 by Compromised by an Expensive Non-functioning "Touch" Feature This review is of a Delta Faucet 9159T-AR-DST Trinsic Single Handle Pull-Down Kitchen Faucet Featuring Touch2O Technology, Arctic Stainless installed in March 2014. Even after a five hour installation attempt by a licensed plumber, carefully following the included instructions, avoiding any metal-to-metal or electric component overlap, and installing an under sink insulation barrier, plus a service call directly to DELTA seeking advice, we are still without the ability to use this faucet's touted "touch" feature. The problem appears to revolve around an inability to ground the solenoid electronics so that a touch activates the ON / OFF function. Our white-porcelain-over-cast-iron-sink set into a thick granite countertop complicated the installation process, necessitating the need to cut the hard plastic insulation piece to fit. When battery operated, the solenoid allows the water to turn on and off; however, the ability to operate the faucet by touch remains inoperable. Furthermore, the battery connection itself remains intermittent, easily interrupted whenever wires attached to the solenoid pack are jostled. These both appear to be design issues that need to be addressed. Until they are, if your installation involves anything but the most common kind of sink (preferably not made of metal), I would avoid spending the extra for the "touch" feature. If you do decide to go ahead anyway, find a plumber who has installed one with this feature before to assure your best chance for success. The faucet itself looks great; however, we have invested hundreds of dollars for a non-functioning feature and an unnecessarily complicated installation process that seriously mitigates our appreciation of its attractive design.

Rated 3 out of 5 by Not worth the cost It's a faucet, it does what it is supposed to do. However for the money it is not worth it. 1. Does not swing far enough side to side. 2. Full of plastic. 3. The spigot does not stay in the housing very well. 4. The included water supply lines are not adequate, they are stiff plastic lines more suited to what you might find in a house with wheels not an expensive faucet. 5. Anything sets off the touch feature, dish towel touches etc.. I am very disappointed with the quality and craftsmanship of this faucet. Even more so that Delta deleted my first review of this faucet.

Rated 1 out of 5 by Good in theory but not in reality. Overall poor design.... Worked fine at first, then thought the batteries needed replacing, it has been all downhill from there. Inconsistent functionality, the Touch2O rarely works properly, usually no water flow when turned on, have to pull the faucet head in and out to get the water to flow, sometimes cycles rapidly on and off, cannot leave in touch mode because will turn on and off on its own, very difficult to regulate the temperature, etc etc... Was installed by a plumber. Would never recommend the touch feature and have told others not to purchase. A faucet should not be so difficult to install/use this is why I feel the overall design is poor. October 17, 2014
Rated 4 out of 5 by Beautiful faucet, "touch" is a bothersome gimmick. The faucet is beautiful. The "touch" feature is just a bother. I never use it. I just use the faucet by turning on the water the usual way, however when I do that, the water keeps turning off. I paid a lot of extra money for this feature as it sounded like a good idea. I'm taking out the batteries and will just use the faucet without the "touch" feature. So - I would buy a Delta faucet again, just not with the gimmick of "touch". I have other Delta faucets in my house that have been there for 15 years and are still in great condition. It was very difficult to install. November 11, 2012
Rated 2 out of 5 by Frustrating We bought and installed this about a year ago. For the first several months it worked perfectly...then the issues. Coming on by itself, not coming on when tapped, etc. Very disappointed with this product. We researched faucets forever and were convinced we made the right choice. After saving for twol years to re-do our kitchen and splurging for the touch control, I feel foolish and wish I stayed with a traditional faucet. As a military family, we've moved a lot and completed many renovations over the years and we've always used Delta products (faucets, etc) and this is the by far the worst experience we've had.

Rated 1 out of 5 by LEAKS after 1.5 years!! Seriously!!! We built a new house and moved in May 16, 2014. We believed that Delta was the best faucet company over Kohler and Moen based on previous experience. However, after 1.5 years we have four faucets which are dripping non stop. These faucets were purchased directly from Delta.com, we did not buy cheaper models from big box stores because we wanted a quality, well respected and a faucet with longevity. However, I cannot tell you how disappointed we are with these products. We purchased the Addison faucets: Kitchen and Bar/Prep faucet. 2 SEPARATE FAUCETS- BOTH LEAK!! We purchased four: DRYDEN™ TempAssure® 17T Series Shower Trim I think these faucets need to be replaced, and I think it would be horrendous if we were required to AGAIN pay a plumber to install new plumbing fixtures after 1.5 years because of your defective product. Your product promises DIAMOND Seal Technology features a valve embedded with diamonds to ensure like-new operation for the life of the faucet October 10, 2015
