Exactly, to each their own. For me it is the simplicity and ease of use. I don't think a fuomoto would work on the oem housing, and even if it did, the fuomoto type valve Jowett uses has been pressure tested to have redundancy for the vehicle oil pressure. The other big thing for me was my filter wrench was always getting jammed on both the plastic and metal housing. It is just a poor removal design. The motivex looks like a decent alternative to avoid a mess, but it still requires unscrewing a cover and then screwing in this piece vs a flip of a switch. You are looking around $70 for that full setup, which is not bad. With the 15% discount on group buy, you are getting a much stronger housing that is easy to remove. I tried one of these:
and one of these:
and they both sucked, would get jammed, etc., which caused me to try the Jowett housing. It has made the process so much easier, I asked Brian about doing the group buy, and am going to be getting more for family members as Christmas gifts. I don't change my own oil to save money. I actually hate doing it. I just don't trust the techs at lube shops or the dealership and I want a simple process. For me the extra simplicity is worth it for me.
