    New is new, I got what was in the photo nothing else, sent two questions about the item but never received any response, poor communication, and better packaging would be a plus, the item was just put in a box and shipped, no bubble wrap, peanuts, paper packing to keep it from moving around and tight in the box. There was two places in the box where it had come through but did not have any part damaged. Thanks for the deal on the part through all of this, I received the part that I wanted.

    I bought a pair of rotors and only received 1, I didn't know until 3 weeks later when I went to install them. I contacted the seller and they instantly made it right and sent the 2nd 1, excellent customer service, will definitely buy from again and got a great deal. Everything was exactly as described, thanks guys! Great looking, brand new, high quality product.

    Easy to install and great quality

    Merchandise was shipped quickly and packaged well. You have to wrestle with the plastic clam shell, to get the cartridge out of the packaging. Cartridge was easy to install, only needed to align right into position and done! Job took about 20 minutes from start to finish.

    This one is dripping after 16 months !

    These cartridges are a temporary fix for the piece of junk that DELTA now sells, this is my third cartridge in 4 years, will only last 12 to 18 months and start leaking again ! Will never purchase any DELTA products again. I will replace my kitchen faucet with another brand next time it leaks The old DELTA that I had for 20 years only need to replace the rubber seals once at a cost of one tenth of the cost of these cartridges. Review on the above purchase: I am in the hunt for a deal on my 5th one now, if the one I find cost more then $23 I will have paid $7 more for repairs than the cost of the fancy new faucet in almost 5 years !

    This is a great new waterless system!

    These cartridges remove the ball and washer system of old Delta faucets and replaces it with a ceramic flow regulator. The flow was little slow and I took mine apart to make "flow enhancements" by widening the chambers on the ceramic disc. I over worked the channels and needed a replacement cartridge. I made similar changes, removing less material than the first time and I have a great flow and an easy care system. Service tip, the cartridge needs plumbers grease on the ceramic disc for reassembly after being taken apart or the disc may not move freely for you. This is also the cure for a sticky or rough moving handle, a little "plumbers grease" is a lot cheaper then a new cartridge and may fix a small problem fast and cheap. I did not find this fix on you tube, it is my own, When widening ...

    This is a Genuine Delta repair part and it worked perfectly. The replacement job required only 5 minutes. In contrast, I had previously purchased a "fits your faucet" repair part, which was totally non-functional. The repair attempt with the off-brand, defective part wasted about an hour of my time.

    Delta RP50587

    The Delta RP50587 replacement valve cartridge made the repair of a leaky kitchen faucet easy. The repair was a simple removal of the old cartridge and dropping in the new cartridge. The faucet was 6 years old and the two retaining units (a plastic cap that was only hand tightened and a brass bonnet which need to be loosened with a wrench) were not corroded or stuck. The new valve cartridge functions easily and shuts off the water flow completely.
