I have both big and small versions. Only complaint I have is that output hole is a little too big. I solve it by installing a piece of rubber (from bicycle inner tube). This gives a very good filtering. Overall I am very happy with this oil filter ! This bigger one when used with this rubber I mentioned is filtering 22 cal. very efficiently.
looks to be great quality, it took almost 90 days for shipping but I expected that due to COVID-19. I will follow up with how well it works.
