Reason i didn't give 5 stars was since there is no instruction and it is clocked opposite of photo shown it took some time to figure some things out. Like you can swap trumpet and fitting to change clocked angle. Only with looking at other manufacturers i was able to make sure it was set to a good "factory" stiffness/softness to start dialing it in. That is giving the benefit that it also has same pressure internal spring.

So id you're looking for a good quality hybrid BOV and not trying to break the bank this is a great option. Not claiming it is top of the line but confident it will work just fine for my purposes.
