Overall I rate positively, I give a star down for the quality of delivery - 2 of the 3 were as used, which bothers me when I buy "new", but they work and after cleaning ok.
No need for instructions, it's really easy, you can tighten it by hand, you just have to play with the seating so that the head doesn't float - which is related to tightening. Otherwise, I guess it's okay.
easy installation
works
design
not suitable for every valve

Not compatible with Danfos. It has a longer valve stem. Since I damaged it, I can't return it
Nice
