As shown in the attached, we have an antique copper color scheme in our kitchen, which included the primary "pull down sprayer" main faucet on the left. The RO drinking water faucet that matched it went bad and started leaking every time we depressed the lever to pour water, so I had to find a matching replacement. It took a long time to find copper faucets. It is not a common color. After quite a bit of searching, we found one from Westbrass that matched our color. When we got it, we were disappointed to see that the threaded shaft on the Westbrass was only 2" long, which does not fit most granite countertops. The Westbrass was more expensive and on top of that, they offered an extension to their "too short" shaft and wanted an extra $20 for it. Boo on that. We sent it back to Amazon for a refund. So, back to the drawing board to find a matching color that also had a long enough threaded shaft to fit our granite countertop. We finally located the iSpring faucet shown in the attached picture. iSpring has the largest selection of finishes for their RO faucets and they also have a variety of styles in those colors. AND the threaded part of their shaft is 2 1/4" long, allowing it to be mounted in thick countertops. So, this was a lifesaver for us. Although the mounting is drop dead simple, with tool less fittings, and I am a DIY handyman, I hate wiggling into to tight spaces with my hands to attach stuff like this, so I had a plumber come out and do the under-sink contortions to mount it, which took him all of about 5 minutes to remove the old and install this new faucet. And here is even a better part to the story. Unlike many products made in China, by companies that offer poor support, iSpring is totally different when it comes to Customer Service. I was swayed when I read other reviews for this product. If there were any deficiencies, it was very easy to contact iSpring and I noted their response was very quick. SO...I had also noticed a number of review complaints that some very minor adapter parts were missing in an iSpring order, and when contacted iSpring immediately sent out the parts needed to complete the order. iSpring includes two fittings to connect your RO line to the faucet. One of them is a snap fitting that requires no tools....you just slip the fitting onto both connections and you are done (this is what is known as a shark bite fitting). That snap fitting is supplied in a 1/4" to 1/4" connector and they also send a 1/4" to 3/8" adaptor fitting. What is usually missing from an order is the blue plastic "C" shaped lock ring which secures the shark bite connection to the water line at both ends of the fitting. Knowing this, when I ordered my faucet (and before I got it), and not wanting to have my plumber come out a second time, in case one of those little lock rings were missing, I emailed iSpring through the Amazon link and asked for them to send me the little connector kit with both sizes of the blue plastic lock ring. They agreed instantly and I received the "precautionary" parts a couple days later. My RO faucet arrived two days after that and sure enough, the larger lock ring that secures the 3/8" side of the step-down adapter was missing from my kit. But having the replacement "precautionary" fittings from iSpring, insured that I had all the parts necessary for my plumber to install on his initial trip. The iSpring customer service rep said that my RO faucet should include everything needed but evidently iSpring does not have that under control, to avoid a small missing part. You might want to do what I did and request the small connector/adapter kit, specifying that you want the needed lock rings as well. Don't hesitate to order from iSpring. You will be very happy that you did, in spite of a very minor shortcoming.
