The editorial review of the product highlights a mixed yet largely positive customer experience, particularly emphasizing the product's installation process and the responsiveness of the seller and manufacturer. Customers reported that the installation was straightforward; however, there were specific challenges related to compatibility with existing plumbing systems. One user noted issues with the saddle fitting due to plastic undersink piping and a mismatch with the threaded T-fitting, which required direct communication with the manufacturer for resolution. The customer appreciated the support they received during this process, indicating a proactive customer service approach from both the seller and the manufacturer. Additionally, some users encountered leaks with the pre-installed canisters, which required a simple fix involving oiling the O-rings and re-tightening them. Despite these hurdles, overall sentiment leaned towards satisfaction, with one long-term user (who has now replaced the cartridge after three years) expressing their contentment with the product and rating it four stars. These experiences suggest that while customers may face initial challenges, effective customer support can enhance the overall satisfaction with the product. **
