Grohe kitchen faucets have lifetime warranty on their Ceramic cartridges. I found Grohe cartridge on Wayfair by searching on Google and it seemed to be the correct cartridge. There was no charge on my Wayfair order form, but I expected a shipping charge so I provided my Visa information. Then I saw on my Visa statement that $52.99 had been charged, plus shipping $6.89. Other consumers should not provide their Visa info to this company.

As expected and good price.

Excellent quality

Fit perfectly on my faucet and the price was great

The pressure in my sink was so little that it barely dribbled. The filter cartridge did the trick. Thank you for the help in finding this.
