Delta 4380-DST Reviews

Rated 5 out of 5 by from Spectacular The faucet is fabulous! The champagne bronze finish is warm and rich, and a beautiful complement to my new ivory integrated sink and light-tone quartz counter. Functionality is perfect--not a bit of spray or splash despite the height. It is easy to keep neat as there aren't any crevices. Not having a base plate shows the richness even more. The champagne bronze is gorgeous! I've had it for over a month and it is striking! So happy I found it!!

Rated 4 out of 5 by from good looking faucet Purchased and installed faucet about a month ago. Looks great on my kitchen. Works very well. Some comments: Can't attach a PUR faucet filter. Had to buy an undercounter water filter. Spray nozzle does not attach securely to base. Needs to have a tighter fit. Other than those, great buy.

Rated 5 out of 5 by from High Quality This is an elegant set, better than I expected. I installed it in a granite countertop with no issues. The quality seems to be the best and I expect it to be trouble free for many years. All the parts were well marked and the instructions were good. I also bought the soap dispenser. Shipping was prompt.

Rated 4 out of 5 by from stuck sprayer Had this installed in our new house last year. Loved it until recently when the sprayer handle decided to stay stuck in the on position. Trying to pull it out so the sprayer would turn off was a real adventure at times. I love the look and functionality of the faucet itself and would not choose another. It's so sleek and modern but guess I'll have to contact Delta about the sprayer.

Rated 5 out of 5 by from Great Purchase I am very happy with my new faucet assembly. It has increased the power of the water coming from the faucet; it is aligned perfectly with the drain in my sink; and it just looks very nice. It arrived even more quickly that the least number of days promised, and I had excellent help with a customer service assistant when trying to order it on the internet. He talked me through it over the phone while I was logged onto this site.

Rated 5 out of 5 by from Very Satisfied -- Love Design I especially liked where the button is on the sprayer. Relocated from the typical design by making it more ergonomically placed for the THUMB to press. This makes more sense as one grabs the sprayer to use it. The thumb's muscles are stronger, typically. The design is elegant, too, like a "swan's neck". The design makes me smile every time I look at it.

Rated 5 out of 5 by from New kitchen faucet We bought this faucet to replace a similar one that we had in a stainless steel finish (we wanted a darker finish). We had some issues with the faucet leaking, so I sent an email to customer service. They wrote back promptly, said that Delta wanted issues referred straight to them, and Delta sent out a replacement part the next day.

Rated 5 out of 5 by from Great Faucet... easy installation Ordered this to replace the leaking one that we had. our sink is relatively shallow and we had problems cleaning large pots due to the height of the old faucet. This one is awesome. it makes the sink appear deeper! So far we have had it two months and it works great. I installed it myself with the directions included and had no problem at all!
