I am a home builder, specializing in Passive House (the most energy efficient house anyone can build) and I have been using and installing the 6 stage RO system for my clients for years. I just replaced my own set of filters this morning and it went flawlessly. The smaller filters have even been upgraded to 'push in' fittings, reducing the need for adapters even farther. My only criticism would be to include detailed instructions on your product pages, website AND in the box with EACH filter type. I was fine, but my new PM, who just installed one of these in her home, had some issues understanding what to do.
